feat: T6 wave 3 – treatment books from lot, label print lock, restricted zone, authority notices

- Treatments book their dose from a medicine lot (delta booking on edit,
  bulk all-or-nothing, idempotent); Bestandsbuch columns from the lot,
  FEHLT exactly where treatmentLogGaps reports a gap; Bestandsbuch export
  needs veterinary-medicines:read.
- Label printing: 409 LABEL_PARTICULARS_MISSING on gaps, proof print with
  watermark, PRINT audit before the PDF, check endpoints; digit rules only
  from the seeded ComplianceSettings row (fail closed).
- Restricted zone (Berlin day): create, update, move, merge and CSV import
  blocked inside an active restriction; override with reason and
  compliance:manage, audited, never stored on the colony; split, harvest
  and dissolve stay free; restriction details only with compliance:read.
- Authority notices: settings, herd snapshot, registration/herd change/TSK
  notices with one open draft per kind under the settings lock.
- Label check refinements (geometric reading order, number|unit pairs).
- ARCHITECTURE.md §12.6–12.8, Annahmen 71–77; spec §5.6 Berlin day.
