feat: T4 wave 3 - notifications per user, suggestions API, varroa bands, split/queen events

- Schema III: per-user notifications (broadcast fan-out migration,
  category, link, requiredPermissions filter), notification preferences
  and settings endpoints, calendar withdrawal switch, occupiedFrames
- Suggestions API: list/summary with permission visibility and paging,
  accept/dismiss/reopen incl. bulk, SuggestionView on all responses
- Varroa traffic light by season and method, young colonies, treatment
  effect window, sample-based percentage; shared withdrawal-window helper
  on Berlin calendar days; GET /varroa-measurements/thresholds
- ColonySplit and QueenAssigned domain events with calendar and webhook
  handlers
- Outbox claims compare against now() rounded to timestamp(3); fixes the
  flaky e2e claims of rows written with SQL now()
