Show as much of a month event title as fits (#164) (#183)

Month-view event titles no longer truncate with "…". `MonthBar` — the single
chip renderer for every month style and for the drag's floating copy — now uses
`TextOverflow.Clip` with `softWrap = false`, so a title runs to the chip's edge
and clips mid-glyph instead of spending two characters' width on an ellipsis.

`softWrap = false` is load-bearing: `Clip` on its own still breaks a `maxLines = 1`
line at the last whole word, so "Team standup meeting" would render as "Team" —
less title than the ellipsis showed, not more.

Deviation from the issue: right-to-left layouts keep the ellipsis. With
`softWrap` off Compose lays the line out at its full intrinsic width and clips to
the node's left edge, which in RTL is the *end* of the string — an Arabic title
would have lost its beginning. `Ellipsis` truncates at the logical end in both
directions, so RTL keeps it.

The Glance month widget needs nothing: its `Text` has no overflow parameter, and
a RemoteViews `TextView` with `maxLines = 1` and no ellipsize already clips.

Closes #164

 ## [Unreleased]
 
+### Changed
+- Month-view event titles no longer end in an ellipsis. The "…" took the width
+  of a couple of characters and told you nothing you couldn't already see, so
+  the title now simply runs to the edge of its chip — a few more letters per
+  cell, which is often the difference between two events you can tell apart and
+  two you can't ([#164]).
+
+## [2.19.1] — 2026-08-11
+
+### Added
+- **Drag to reschedule can be turned off.** Settings → Views → *Drag to
+  reschedule*, on by default. Off, no event can be picked up in the month, week
+  or day view — for anyone who kept moving appointments by accident while
+  scrolling ([#173]).
+- An early Brazilian Portuguese translation. Calendula has started speaking
+  Brazilian Portuguese, contributed as a community translation through
+  [Calendula's Weblate](https://weblate.dev.jeanlucmakiola.de/projects/calendula/).
+  About a third of the app is covered, so the rest still shows in English — you
+  can pick it under Settings → Language or in Android's per-app language
+  settings. Thanks to
+  [bkrz](https://weblate.dev.jeanlucmakiola.de/user/bkrz/) for getting it
+  started; help finishing it is very welcome.
+
+### Fixed
+- **The language picker forgot which language was picked.** Android hands the
+  applied language back with its script filled in — Simplified Chinese goes in
+  as `zh-CN` and comes out as `zh-Hans-CN` — so after a restart no entry in
+  Settings → Language showed as selected, and the row above it named the
+  language the long way round. Only languages that imply a script were
+  affected.
+
+## [2.19.0] — 2026-08-10
+
+### Added
+- **Drag an event to reschedule it.** Press and hold an event in the month,
+  week or day view and drop it on another time or day — the only way to move an
+  appointment used to be opening it and editing its start and end by hand. The
+  block follows your finger, the timeline scrolls when you carry it to an edge,
+  and the event's length is preserved: a 90-minute meeting dropped on 09:00 ends
+  at 10:30. In week and day view the drop snaps to 15-minute steps; in month
+  view it moves the event to the day you dropped it on and leaves the time
+  alone. A confirmation names the new slot and offers **Undo** wherever the move
+  can be taken back in one step. Events you can't edit — read-only calendars, and
+  birthdays and anniversaries mirrored from your contacts — can't be picked up.
+  Rescheduling isn't pointer-only: a screen reader gets a **Move…** action on
+  every event that can be moved ([#68]).
+- Dragging a **recurring** event asks what it should apply to, the same *this
+  event / this and following / all events* choice a save does. Where moving the
+  whole series would change which weekday it falls on, the rule is rewritten to
+  match — a weekly Monday event dropped on a Wednesday becomes a weekly
+  Wednesday event. Where it can't be rewritten safely, the prompt says so and
+  offers to move just the one occurrence, rather than quietly leaving the
+  series behind ([#68]).
+- **Delete several search results at once.** Long-press a hit in search to enter
+  selection mode, tap the rest (or **Select all**), and delete the lot in one
+  action — finding and removing, say, every leftover event with the same title
+  no longer means opening them one at a time. Recurring hits in the batch ask
+  once for the whole selection instead of once each, results on read-only
+  calendars can't be selected, and the deletion is confirmed before it runs
+  ([#80]).
+
+### Changed
+- **First launch is now a short wizard** instead of a single permission screen.
+  It counts its steps, each one can be stepped back out of, and beyond granting
+  calendar access it offers two things worth deciding once: turning on automatic
+  backup — chosen inline, folder picker and all, since events that live only on
+  the phone are lost with it — and choosing which view Calendula opens on, with
+  a live preview of the month, week, day and agenda layouts rather than four
+  names in a list. Both are skippable, everything chosen is changeable in
+  Settings afterwards, and the backup step is offered only where nothing
+  writable is being synced anywhere. Existing installs are not re-onboarded —
+  revoking and re-granting the calendar permission later does not restart the
+  wizard ([#163]).
+- The one-time notice about calendars switched off for this device is now a step
+  in the flow rather than a dialog thrown over the app on first open.
+
+### Fixed
+- Removed the deprecated `statusBarColor` / `navigationBarColor` theme
+  attributes the Play Console flags on Android 15 and up, where they no longer
+  do anything. The launch backdrop now picks its status-bar icons from the
+  light/dark resource instead, so they stay legible over it either way
+  ([#123]).
+
+## [2.18.1] — 2026-08-06
+
+### Fixed
+- Tapping an empty slot in week or day view creates the event at the hour you
+  tapped, after the timeline has been zoomed. Pinching the day taller or shorter
+  — or changing **Hour height** in Settings — left the tap still being measured
+  against the old spacing, so the new event landed at some other hour entirely
+  ([#148]).
+

+### First-launch wizard
+
+`ui/onboarding/` is a plan, not a navigation graph: `onboardingPlan()` is a
+pure function of the stored answers that returns the whole flow *plus* the
+step it is on, and `RootScreen` renders that step. Two rules make it work:
+
+- The plan keeps **completed** steps, so finishing one never renumbers the
+  counter under the user, and stepping *back* is just clearing the previous
+  step's answer — there is no separate back stack. The calendar grant is the
+  one step with nothing to return to, so back stops there.
+- The optional steps (backup, view) only exist for an install still on its
+  first run — `armOnboardingWizard()` arms on any launch holding the calendar
+  permission but refuses if the reminder step was already answered, and the
+  closing screen clears the flag again, so revoking and re-granting the
+  permission later never re-onboards anyone.
+
+Whether the backup step applies (nothing writable is synced anywhere) cannot
+be known before the grant, so it is assumed until the calendar list can be
+read: the flow may shrink after the grant, never sprout a step the counter
+had not accounted for.
+
+The flow closes on an "all set" screen, and the one-time calendar-visibility
+notice (#75) is a step in front of it rather than a dialog over the app — it
+is the only optional step an *already onboarded* install can be given, which
+is why it alone is not gated on the wizard being armed.

 - All-day events are normalised to UTC midnights with an exclusive end.
 
+### Drag to reschedule
+
+Dropping an event on another slot (#68) is not a second write path: the drop
+loads the event, prefills the **same** `toEditForm` the edit screen uses, shifts
+it (`EventShift.kt`), and dispatches through the same three repository calls a
+save does — so recurring writes, reminder reconciliation and attendee
+preservation behave identically. The full form is carried through, never a
+stripped one: `updateOccurrence` reconciles reminders *and* attendees onto the
+new exception row, and a partial form would wipe them.
+
+Two things the drag has to get right that the edit screen sidesteps:
+
+- **`RRULE` day parts go stale.** `buildEventUpdateValues` writes the rule
+  verbatim while `DTSTART` moves, so dragging a `FREQ=WEEKLY;BYDAY=MO` occurrence
+  onto a Wednesday under *All events* leaves a Wednesday anchor under a Monday
+  rule and the series does not move. `realignRecurrence` re-derives `BYDAY`, and
+  returns **null** for everything else — the drop then offers only *this event*,
+  whose exception row carries no rule at all. The same staleness is reachable
+  from the edit screen; wiring it there too is a separate change.
+
+  What the rule has to agree with is the **series anchor**, not the occurrence
+  being dragged, and `buildEventUpdateValues` moves that anchor by the same
+  *wall-clock* shift. So the realigner only touches weekday, which is uniform mod
+  7 and therefore survives that shift whatever time of day the anchor sits at.
+  Day-of-month is not uniform — `BYMONTHDAY=28` with a January anchor, occurrence
+  Feb 28 dragged to Mar 1, would leave a Jan 29 anchor under a `BYMONTHDAY=1`
+  rule, a DTSTART that is not an instance of its own rule and a phantom
+  occurrence on any client that trusts it.
+
+  Uniform mod 7 is not enough on its own: the anchor also has to cross the *same
+  number of midnights* as the occurrence did, or the rebuilt weekday is off by a
+  day. `RescheduleViewModel` requires that of every write wider than one
+  occurrence, in the two shapes a drag comes in:
+
+  - a drag that **changes the day** must be a whole number of days, so the two
+    move in step whatever the anchor's time of day;
+  - a **time-only** drag must leave the anchor on its own day. That is normally
+    free, since the anchor shares the occurrence's time of day — but a row with
+    no `EVENT_TIMEZONE` resolves anchor and occurrence in zones that can sit a
+    DST hour apart, and a near-midnight drag would then carry the anchor across a
+    midnight the occurrence never crossed.
+
+  Whatever falls outside — a rule the realigner won't rebuild, or a shift that
+  would move rule and anchor out of step — may only move the one occurrence.
+
+  The accepted parts are deliberately a **subset** of what `parseSimpleRecurrence`
+  understands, so anything realignable is also a rule whose `UNTIL` the guard
+  below can actually read.
+- **The eligibility gate is load-bearing.** Nothing below the UI refuses a
+  write, so `CalendarSource.allowsEventMove` is what keeps read-only and
+  contact-managed events from being dragged. It is deliberately *not*
+  `isEventTarget`: a managed event is editable (reminders, notes) yet must never
+  move, while a switched-off calendar renders nothing to grab anyway.
+
+A drop that would push a series past its own `UNTIL` — the provider then
+generates zero occurrences and the event vanishes from every view — is refused
+rather than written. The check happens at **write** time, not at drop time,
+because which date has to clear `UNTIL` depends on how far the write reaches: a
+whole-series move carries the *anchor*, a split starts a new series at the moved
+occurrence, and a single occurrence becomes an exception row that no `UNTIL`
+constrains. Testing the occurrence in every case would refuse the perfectly
+ordinary drag of a bounded series' last occurrence.
+
+**One drop is written at a time.** Two drops of the same recurring event landing
+inside one write window would each compute their shift from the same pre-move
+occurrence, while the data layer applies both to the re-read anchor — so the
+shifts would compound. `RescheduleViewModel.move` therefore refuses while a write
+(or its scope dialog) is outstanding, and says so in its return value: the view
+that took the drop releases the block it was holding on the target instead of
+waiting out a settle that will never arrive.
+
+Two known limitations of a whole-series move, both shared with the edit screen's
+own *All events* time save rather than introduced here — a drag just makes them
+one gesture away: the series' `EXDATE` stamps and its exception rows are **not**
+re-anchored, so previously deleted occurrences can reappear and previously
+modified ones stay behind while the rest of the series moves.

+`DTSTART` and `DTEND`/`DURATION`/`RRULE` are written — so a concurrent remote
+edit to the title, notes or guests survives untouched. What a drop *can* clobber
+is a concurrent remote **time** change, and parking a one-gesture action behind a
+modal would cost more than that case is worth; the undo on the confirmation chip
+is the answer instead. Undo restores semantics, not the row's byte
+shape (`DURATION` normalises to `P<n>S`/`P<n>D`, `EVENT_TIMEZONE` is stamped
+concrete), and it is offered only where the inverse is one symmetric write — a
+one-off event or a whole-series shift. *This event* leaves an exception row
+behind and *this and following* splits the series; neither is undone by shifting
+back, so both get a plain confirmation. Two further gaps, both narrow and
+accepted: a shift whose *anchor* crosses a DST gap is not invertible in wall
+clock (the −Δ normalises back to where it started), and an undo after a
+concurrent remote time change overwrites it, exactly as the forward move would.
