test: skip integration tests by default, require -m integration to run

Integration tests in test_wal_live_recovery.py need a running server and
fail in CI with 'ModuleNotFoundError: No module named requests' because
the test environment doesn't have requests available in the test Python
path (it's only in the hermes-agent venv). Rather than fixing the
Python path issue, skip these by default with the standard
@pytest.mark.integration marker and a conftest hook that auto-skips them
unless -m integration is passed.
