feat: T6 wave 1 – compliance schema, permissions, lock order, backup

- Migrations (additive): veterinary medicines with lots and movement
  ledger, treatment medicine/lot/dose links, label particulars, authority
  notices, apiary restrictions, compliance settings and acknowledgements;
  notification category COMPLIANCE, added to non-empty Telegram lists.
- Permissions veterinary-medicines:* and compliance:* with role grants.
- LOCKABLE_TABLES: Apiary locks before Colony; T6 tables appended.
- Backup exports and restores the new tables in FK order; unsealed files
  skip them and report dropped medicine links; an open TSK draft in the
  target wins.
- describeNullContracts shared helper; Telegram backlog e2e no longer
  depends on the time of day.
