feat: T4 wave 10 – bottling quality, phenology and honey chain UI, Telegram link/receive and ops

- Bottling quality: water content above the legal limit (strict >) answers
  409 CONFIRMATION_REQUIRED bound to the measured value; prefill for jar
  size, best-before (shelfLifeMonths, month-end clamping) and water content;
  impossible dates give 400; water-content checks in src/common/quality.
- Frontend phenology: "Entwicklung melden" sheet, IndexedDB v4 queue,
  season header on the apiary page, confirmed revoke for all apiaries.
- Frontend honey chain: "Vorschlag aus …" hints with explicit take-over,
  prefill status note, movement ledger with withdraw/correct dialogs.
- Telegram: link tokens (hashed, single use), private-chat receiver with
  lease and offset CAS, bounded poison-update skip, Retry-After, pending
  deliveries skipped on disconnect; system API for deliveries and retry;
  worker-only secret wiring and manifest policy tests.
- ARCHITECTURE.md §7, §9, §10, §11.11–11.13, Annahmen 51–55.
