feat: add ComfyUI integration for image generation and management

- Implemented ComfyGenerateRequest type and associated functions for generating images using various architectures and modes.
- Added functions for listing generation options and handling image uploads.
- Created workflows for different generation modes including SDXL, Z-Image, Z-Image Turbo, and Anima.
- Introduced GenerationJobStatus component to display the status of ongoing generation jobs.
- Developed MaskControls for managing mask operations and displaying mask analysis.
- Created palette items for tool selection, layer management, and generation settings.
