Branch 1 of 2 for v2.7 (the .ics topic). Adds the write side of a
hand-rolled RFC 5545 engine (zero deps, stays on kotlinx-datetime):
- domain/ics: IcsText (escape + 75-octet folding), IcsEvent model,
IcsWriter.writeCalendar. Timezone rule: all-day VALUE=DATE, one-off
timed UTC Z, recurring timed TZID-labelled from EVENT_TIMEZONE (no
VTIMEZONE — import resolves TZID against the OS tz db).
- Single-event share from the detail screen (FileProvider + ACTION_SEND).
- Whole-calendar backup of the writable local calendars to a SAF file
(Settings -> Calendars -> Export as .ics), one combined VCALENDAR.
- insertEvent now writes Events.UID_2445; legacy rows fall back to a
stable synthesised UID at export time so a later restore won't dupe.
- EXDATE / RECURRENCE-ID overrides are deliberately skipped this pass
(documented v1 limit; import will skip them too).
Engine + mapper unit-tested. Import (Branch 2, feat/ics-import) ships in
the same v2.7 release; no tag until both land + on-device review.

Make the supported-language list a single source of truth so community
translations show up with no code change: add res/xml/locales_config.xml
(en, de) and reference it via android:localeConfig, which also surfaces the
per-app language entry in Android 13+ system settings.
Rewrite AppLanguage to parse locales_config.xml for the supported BCP-47
tags and expose currentTag/apply/displayName (autonyms), dropping the
hardcoded LanguagePref enum; the Settings picker is now built from that list.
Remove the now-unused settings_language_german/english strings.
Adding a language is now: drop in values-<tag>/strings.xml and add one
<locale> line.

Bundles the unreleased Tier 2/3 work into one release:
- Home-screen widgets (Glance): an "Upcoming" agenda widget and a month-grid
widget, both reusing the in-app grouping/layout (groupAgendaDays,
layoutMonthWeeks) via a Hilt WidgetEntryPoint, honouring hidden-calendar
filters and refreshing on PROVIDER_CHANGED / date rollover.
- App shortcut: launcher long-press "New event", routed through the shared
WidgetNavRequest.Create channel into the create-event form.
- Agenda view and jump-to-date (already merged via #3/#4) are documented here
as part of the shipped version.
Bumps versionCode 20500 / versionName 2.5.0, moves the CHANGELOG Unreleased
section under [2.5.0], updates ROADMAP/STATE, and adds EN+DE strings.

READ_CALENDAR permission declared. Strings split into English master
(values/) and German (values-de/) with the Loading/Failure/Success
generic state strings used across screens. Backup rules let DataStore
back up by default with no file-based content. Theme stub delegates
real theming to Compose; the Activity-level XML theme only sets
transparent system bars and dark-mode hint.
