feat: T4 wave 5 - colony end cleanup, withdrawal chain, next steps, inspection takeover UI

- Colony end releases the queen in the same transaction; open
  suggestions become obsolete and a CLEANUP suggestion lists open
  tasks and the queen; apply-cleanup validates evidence and blocks
  reactivated colonies
- Withdrawal chain: plausibility warnings on harvest and bottling,
  conflict notifications also when a treatment is entered or corrected
  after the harvest (naming bottled lots), withdrawal spans in the
  calendar and M365 sync, Berlin-day end events
- Next 3 steps per colony and the "Heute" endpoint with ranking and an
  explicit merge table by intent
- Inspection-triggered rule suggestions follow the colony's latest
  inspection (resolve when the finding is gone, refresh when it stays)
- Frontend: colony card takeover in the inspection form, feed status as
  condition, occupied frames 0-40; legacy offline entries keep syncing
- Notifications and preferences are deleted with their user
