fix: catch RouteNotFoundError, guard missing env vars, register marker

- Catch RouteNotFoundError alongside MakeTargetError in the
  deployed_agent fixture so route lookup failures produce a clean
  test failure instead of an uncaught exception
- Validate BASE_URL and MODEL_ID are set before writing .env,
  failing with a clear message instead of a raw KeyError
- Register @pytest.mark.integration in root pyproject.toml to
  suppress PytestUnknownMarkWarning
