chore(entrypoint): remove runtime uv installation; rely on Dockerfile-provided uv

- Drop runtime installer for uv; uv is now baked into the image via Dockerfile.
- Keep pip preflight (ensurepip) and toml preinstall to satisfy ComfyUI-Manager’s prestartup requirements.
- Retain unified torch-based GPU probe, SageAttention setup, custom node install flow, and ONNX Runtime CUDA provider guard.
