fix(test): convert M1-M6 E2E suites to real subprocess CLI invocations (closes #658)

Replace CliRunner + unittest.mock.patch with subprocess.run for all
21 CLI-facing test functions across the M1-M6 E2E verification helpers.

Application code fixes:
- action.py: _get_lifecycle_service() uses container.plan_lifecycle_service()
- plan.py: _get_lifecycle_service() uses container.plan_lifecycle_service()
- plan.py: three container.resolve(DecisionService) → container.decision_service()

Test infrastructure:
- New robot/helper_e2e_common.py with shared subprocess utilities
  (run_cli, setup_workspace with DB migrations, cleanup_workspace)
- M1-M4, M6 helpers refactored to use run_cli() with real SQLite DB
- M5 unchanged (0 CLI tests, all domain-level)
- TDD detection updated to recognise run_cli() as subprocess invocation
- Remove @tdd_expected_fail from TDD feature + robot tags
- Update 8 Behave step files that mocked container.resolve() to use
  container.decision_service() / container.plan_lifecycle_service()
