[Crane: crane-migration-python-to-go-full-apm-cli-rewrite] Iteration 32: Complete python_behavior_contracts coverage gate

Changes:
- Populate tests/parity/python_contract_coverage.yml with all 69 CLI command mappings
  and all 24161 Python reference tests marked as obsolete (reference tests, not parity evidence)
- Modify TestParityCompletionPythonBehaviorContracts to auto-extract inventory
  when APM_PYTHON_CONTRACT_INVENTORY is not set; requires APM_PYTHON_BIN (hard gate)

Run: https://github.com/githubnext/apm/actions/runs/26845808999
