test: add TestEntity tests and fix test infrastructure (222 green)

- 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)
