fix: correct Manifest/ManifestIndex usage and add missing type annotations in tests

- test_docker_launch_committed_image: replace Manifest.from_json_obj
  (nonexistent) with ManifestIndex.from_json_obj; pass manifest= arg
  to DockerBottlePlan constructor (required by BottlePlan base class)
- test_macos_container_launch: cast SimpleNamespace stubs to their
  expected types (BottleSpec, GitGatePlan, EgressPlan) in _build_plan;
  add str type annotations to fake_build parameter signatures
- test_macos_container_util: add str type annotations to fake_build_image
  parameter signatures
