Completes v2.7 Branch 2. Wires the import core into the app:
- Manifest ACTION_VIEW/SEND for text/calendar; MainActivity parses the
incoming Uri (content/file only, so calendula:// deep-links don't match)
and routes it through RootScreen → CalendarHost like the other one-shot
intents.
- ImportViewModel reads + parses the file and routes by count: one event →
the prefilled create form for review (EventEditViewModel.openImported,
which freezes the reminder default so the file's reminders win); many →
ImportScreen with a writable-calendar picker, then a bulk import (UID
dedup) and a result summary.
- ImportScreen also surfaces parser warnings (skipped recurrence overrides,
ignored attendees, unknown-timezone fallback). Strings EN+DE.
Package is ui.imports (not ui.import — Java keyword). lint + test +
assembleDebug green. No v2.7 tag until on-device review.
