Integration: wire 3 new P2 screens into App.kt nav + HapticsInit bootstrap

Navigation wiring (per follow-ups flagged by Streams G/H/I):
- Add TaskTemplatesBrowserRoute (new) + App.kt composable<TaskTemplatesBrowserRoute>
- Wire composable<TaskSuggestionsRoute> (declared by Stream H but unwired)
- Wire composable<AddTaskWithResidenceRoute> (declared by Stream I but unwired)

MainActivity.onCreate now calls HapticsInit.install(applicationContext) so the
Vibrator fallback path works on non-View call-sites (flagged by Stream S).

Deferred cleanup (tracked, not done here):
- Port push-token registration from legacy MyFirebaseMessagingService.kt to
  new FcmService (Stream N TODO).
- Remove legacy WidgetTaskActionReceiver + manifest entry (Stream M flag).
- Residence invite accept/decline APILayer methods (Stream O TODO).
