feat: T6 wave 2 – medicine book, document rights, label particulars, herd events

- Veterinary medicine catalogue, lots and append-only movement ledger
  (rest always computed; corrections as counter-bookings; inactive
  medicines take no new stock; unit must match on lot moves).
- Documents of medicine lots, authority notices and restrictions need the
  domain right on top of documents:* (403 before any lookup).
- Label particulars: pure checkLabel with six mandatory gaps and four
  warnings, AFM font metrics, Berlin-day dates, geometric reading order
  for split addresses, new master-data fields with row-locked updates.
- Herd events ColonyCreated, ColonyMoved, ApiaryChanged and
  TskReferenceDayReached (ids only, never forwarded to webhooks); CSV
  import emits ColonyCreated with audit.
- ARCHITECTURE.md §12 Compliance (T6), Annahmen 59–70.
