fix(worker): S2 proactive tips logic, i18n parity, hardened test DB reset

- processProactiveTips now iterates all expiring items sorted by urgency and
  emits the first candidate with a recipe that clears 7-day dedup.
- Add pt-PT proactive-tip templates; remove en-GB duplicate; parity test
  asserts against shared-types SUPPORTED_LANGUAGE_TAGS.
- Serialize DB test setup via turbo dependencies; seed truncates only *_test
  DBs, guarded by both --test flag and DB name suffix.
