The "Continuous Integration" workflow (Performance Tests + API
Documentation jobs) has failed on every main commit since the API start
path was exercised: pose_service._initialize_models() called
`DensePoseHead()` with no args, but DensePoseHead.__init__ requires a
config dict → "TypeError: DensePoseHead.__init__() missing 1 required
positional argument: 'config'" → uvicorn "Application startup failed".
Pass a config: input_channels=256 (matches the modality translator's
output), num_body_parts=24 (DensePose standard), num_uv_coordinates=2.
Both call sites (with/without pose_model_path) fixed.
Verified locally: DensePoseHead(config) + ModalityTranslationNetwork(config)
both construct + eval, clearing the startup TypeError.
