feat(media): add ComfyUI local image generation provider

This PR adds ComfyUI as a media provider for local image generation.
Following maintainer guidance, this keeps ComfyUI in the media-provider
flow and does NOT touch the BYOK/SettingsDialog logic (deferred to follow-up).

Changes:
- Daemon: renderComfyUIImage() function with OpenAI-compatible API contract
- Daemon + web: MEDIA_PROVIDERS entry with integrated=true, credentialsRequired=false
- Daemon + web: comfyui-sdxl model in IMAGE_MODELS (default: true)
- Web: NewProjectPanel whitelist for 'comfyui'
- Web: provider-readiness.ts already supports credentialsRequired=false (no changes needed)

ComfyUI is now available as a local, keyless image generation provider
accessible via Open Design's standard media generation flow.
