Summary

• Migrate remaining mock-based app service tests from
  api/tests/unit_tests/services/test_app_service.py (609 lines, 19 tests) into
  the existing testcontainers integration test at
  api/tests/test_containers_integration_tests/services/test_app_service.py
  (1144 lines, 19 tests).

• The existing testcontainers file covered app CRUD, pagination, update operations,
  deletion, app meta, and code lookups. This PR adds 5 new integration tests for
  error paths: code/ID lookup not-found errors, empty metadata when workflow/config
  missing, and None return for empty tag filter. Then removes the fully superseded
  609-line mock-based file.

Part of #32454
