Expand test suite to 51 tests with full CRUD coverage

Test collections: calendar-test, contacts-test, /mcp-tests/
- OAuth: 30 tests (metadata, credentials, PKCE, rejection, tools list × 5 servers)
- Mail: 5 tests (accounts, folders, search, empty search, read full mail)
- Calendar: 5 tests (list, tasks, create event + verify, create task + verify, date range)
- Contacts: 4 tests (search, empty, create + verify, get details)
- Files: 6 tests (list, info, write+read+delete, create+delete folder, move, search)
- Notes: 1 test (list notebooks)

All tests create unique timestamped data and clean up after themselves.
