validate_as_red/blue_lead now delegate to TestEntity. check_dual_validation routes through entity instead of assigning test.state directly. Side effects dispatched via domain events. Entity raises InvalidOperationError for backward compat. Removed 4 dead V1 xfail tests, fixed 2 real test issues. 224 passed, 0 xfailed.
- Add test_test_entity.py with 46 pure unit tests covering the full domain entity
- Fix _FakeSettings in 11 test files (REPORT_TEMPLATES_DIR, JIRA, TEMPO)
- Fix stale db.commit assertions to db.flush after UoW refactor
- Add missing mock fields for TestEntity.from_orm compatibility
- Make database.py skip pool args for SQLite in test environment
- Disable slowapi rate limiter in test client fixture
- Inject test engine into app.database to fix threading errors
- Update role assertions to match current require_any_role policy
- Mark 6 legacy V1 endpoint tests as xfail (replaced by V2 workflow)
