test(handlers): add unit tests for matchesChatID, QueueDepth, QueueStatusByID, queueRowAuthFields

- matchesChatID: 8 cases covering exact match, prefix, comma-separated, absent key, whitespace
- QueueDepth: add QueryMatcherEqual to both tests; was defaulting to regex matcher where
  'queued' single-quoted in regex matched individual chars instead of the string
- QueueStatusByID: Success, NotFound, DBError, CompletedWithResponse
- queueRowAuthFields: Success, NotFound, DBError
- Fix unused variable (callerID in TestQueueStatusByID_Success)
