A dedicated sub-page under Settings drives the mirror:
- master enable toggle — requests READ_CONTACTS contextually (only here, never at
startup), runs an immediate sync on enable, and on disable confirms then tears
the managed calendars down;
- per-type toggles (Birthdays / Anniversaries / Other), each confirm-guarded
since turning one off deletes its calendar;
- an editable title template ({name}/{age}) and a Show-age toggle;
- a "Sync now" row with the last-run time, a paused/permission banner with a
re-grant button, and a pointer to per-calendar colour/visibility/reminders.
Exposed via a separate SpecialDatesUiState flow (the main settings combine is
already at capacity); the ViewModel gained the engine/scheduler wiring.
