chore: patch project maps after stale backend test cleanup

Regenerate .pi-map*.md artifacts for source changes in:
- apps/api/src/api/tool/tool_types_validation.py
- apps/api/src/schemas/tool/tool_type.py
- apps/api/tests/integration/test_tool_types_api_extended.py
- and all affected test files from backend-frontend refactoring cleanup
