feat: extend offline queueing to all quick-capture forms

Only Durchsicht had an offline fallback (queue to IndexedDB, sync on
reconnect); Behandlung, Fütterung, Varroamessung, Schwarmkontrolle and
Ernte just failed outright with no signal - exactly the situation a
beekeeper is in at the actual hive. Generalizes lib/offline/db.ts and
sync.ts to six queues (version-bumped IndexedDB schema, existing queued
inspections preserved), wires the same "server rejected it vs. no
network" fallback into all five remaining */new pages, and updates the
sync badge to count/drain all six.

Also: doc-hygiene pass (ARCHITECTURE.md/TASKS.md) to replace the stale
pg_dump/CronJob backup plan with the in-app BackupModule that actually
shipped earlier this session.
