test: fix CI failures for path resolution and enum iteration

- Fix test_init_with_absolute_path in test_search_comprehensive.py:
  Use .resolve() for cross-platform path comparison (macOS /tmp -> /private/tmp)

- Fix test_enum_iteration in test_phase_event.py:
  Add missing enum values rate_limit_paused and auth_failure_paused

These are the same platform-specific issues fixed earlier for other tests.
