Merge release/v2.14.0 into chore/floret-implementation

Brings the 2.14.0 feature set (Month week numbers, .ics restore +
per-calendar export picker, Day view on date-header tap, wrapped long
titles, Simplified Chinese) onto the floret-kit migration without
resurrecting the inline component copies the kit now owns.

Conflict resolutions (both were import-block collisions where the
migration repointed to de.jeanlucmakiola.floret.* while release kept the
old app-local imports):

- CalendarsScreen.kt: keep the kit imports (CollapsingScaffold,
  DialogAmountField/DialogUnitDropdown, collapseExit/expandEnter,
  predictiveBack) and repoint FullScreenPicker + positionOf to the kit
  (both moved out of ui.common). Keep the genuinely app-local
  LeadingAvatar/SourceLogo/curatedSourcePackage; drop the renamed
  calendarCollapseExit/calendarExpandEnter (0 uses).
- ImportScreen.kt: keep the app-local CalendarPickerGroups, use the kit's
  predictiveBack, drop the now-unused OptionCard import.

Semantic fixup: CalendarPickerGroups.kt (new in 2.14.0) relied on
same-package resolution of GroupedRow/Position, which the migration moved
to the kit — added the explicit floret.components imports.

Verified: :app:compileDebugKotlin, ./gradlew test (app + kit), and
scripts/check_translations.py all green.
