fix(03): update event lookup test mocks for CR-01/CR-02 query-chain changes

The CR-01 fix appended .orderBy().limit(1) to the edit/delete event lookups
and CR-02 added .innerJoin(calendars).limit(1) to the freshest-etag re-read.
The existing test doubles terminated the mock chain at .where(), so the new
chain calls hit undefined methods → handlers caught the throw and returned 503
(events.test.ts) and the worker skipped the PUT (outboxWorker.test.ts).

Extend the mocks to match the corrected production chains. Behaviour-preserving:
mockWhereCalEvents stays the awaited terminal so etag override assertions still drive.

8 failing tests now green; full suite: api 103, pwa 141.
