release: cut v2.2.0 — tap-to-create + local calendar management

Day/week: tap an empty slot to open the create form prefilled with that
day and the tapped hour (snapped to the hour, 1 h long). Threaded a start
time through CalendarHost → EventEditScreen → openNew; the FAB keeps its
default.

Local calendars: a full-screen editor from Settings → Calendars to
create/rename/recolor/delete device-only calendars (ACCOUNT_TYPE_LOCAL,
sync-adapter insert) with name, pastel-previewed colour, and a description
(stored in CAL_SYNC1). Synced calendars are listed read-only grouped by
account, each with a "manage in source app" deep-link resolved from the
account's own authenticator (DAVx5/ICSx5/…), plus an add-account shortcut;
a <queries> block makes the source apps launchable. Extracted a shared
InlineTextField into ui.common so the event form and calendar editor share
one borderless input style.

Tests: repository delegation + write-failure, mapper isLocal/description,
fake data source extended. Version bumped to 2.2.0 / 20200.

+
+### Added
+- Tap an empty slot in the day or week view to create an event there: the
+  create form opens prefilled with that day and the tapped hour (snapped to
+  the hour, one hour long). Tapping an existing event still opens it
+- Local calendars: create and manage device-only calendars that live
+  entirely on this phone — no account, no sync — from a new "Calendars"
+  screen in Settings. Give each a name, a colour, and an optional
+  description; rename, recolour, or delete them later. Useful when you want
+  a calendar without setting up an account
+- The Calendars screen also lists your synced calendars (DAVx5, ICSx5, …)
+  grouped by account, each with a "Manage" button that opens the app the
+  calendar actually comes from, plus an "Add account" shortcut to the
+  system account settings. Calendula never touches a synced calendar's
+  server itself — that stays with its own app
+
+### Changed
+- Colour swatches in the calendar editor now preview the soft, pastel tone
+  a calendar is actually drawn with, instead of a bright raw colour
+- The calendar editor reuses the event form's field and button styling for
+  a consistent look
+
