fix: T4a browser check findings

- Withdrawal wording from one backend helper everywhere ("bis
  einschließlich TT.MM. – ab TT.MM. wieder erntefähig", year when it
  crosses New Year); withdrawal-status returns lastBlockedDay and the
  ready text, the frontend no longer computes dates
- Calendar events name colony or apiary, withdrawal events carry
  product and detail; compact withdrawal rows on mobile
- One bottling warning per colony and treatment; pre-save hint
- Offline: online-only actions disabled with a reason, cached data
  shows its timestamp, open sheets block submit offline
- Mobile: no horizontal scroll at 360 px, touch targets >= 44 px,
  toasts and the add button no longer cover content
- Cleanup sheet without destructive preselection; natural sort of
  colony codes; collapsible automation rule cards; varroa list newest
  first with chart axes; text fixes
