fix(terminal): avoid lazy-loading tool manifest in async websocket handler

The container-user resolver introduced in 9f72093 accessed
'tool_type.manifest', which triggers a SQLAlchemy lazy load inside the
async WebSocket coroutine and raises MissingGreenlet. Fetch the manifest
explicitly with db_session.get() instead, matching the pattern used in
instance_service.py.

- Replace relationship access with explicit async loads in
  _resolve_container_user().
- Add unit tests covering manifest, base-definition, legacy, and missing
  manifest cases.
- Update project map artifacts.

Quality gates: pytest tests/api tests/services/test_terminal_manager_multi.py tests/unit (247 passed), ruff check (clean).

 ## arch
-Follows pytest-based unit testing architecture with heavy use of mocking (subprocess, filesystem, database) to test services in isolation; tests are organized by service/module with descriptive naming; employs parametrization and fixture-based setup for testing edge cases, error conditions, and path traversal prevention across infrastructure and security-critical components.
+pytest-based unit testing with fixtures for temporary resources (git repos, Docker mocks), heavy use of mocking for external dependencies (Docker, databases), and parameterized tests for cross-platform/git-hosting scenarios.
