fix(connectors): second-pass validation fixes and test coverage

Adversarial re-validation of all four connectors plus a combined-change
regression audit.

- bitbucket: stop declaring incremental sync (deletion reconciliation is
  disabled for incremental runs, so deleted files were never removed on the
  default code configuration); drop a wasted listing round-trip after the
  frontier drains; add 33 tests
- databricks: reject an explicit maxDocuments of 0, which meant unlimited;
  add 34 tests
- google-chat: correct the sender displayName documentation (user auth
  populates only name and type) and emit second-precision RFC-3339 in the
  message filter; 15 -> 24 tests
- workday: fix a crash when maxVersions is persisted as a number; refuse a
  configuration whose status filter Workday did not honor; cap the
  unresolved-name error; 18 -> 27 tests
- document the Google Chat service-account omission
- docs: list all four connectors and correct the connector count
