docs: add docstring to mark_as_cancelled and improve test coverage

- Add comprehensive docstring to mark_as_cancelled() explaining it's reserved
  for future cancellation feature implementation
- Rename test_trigger_ttl.py to test_trigger_cron.py to match module name
- Expand parametrized tests: test all 3 mark functions with 3 retention periods
  (9 combinations) for consistent coverage
- Add 9 new tests covering all trigger_cron.py functions:
  - get_due_triggers (with/without triggers)
  - call_trigger_graph
  - create_next_triggers (success, DuplicateKeyError, other exceptions)
  - handle_trigger (success and failure paths)
  - trigger_cron orchestration
- Total: 18 comprehensive tests with timezone-aware datetime assertions
