fix: rebuild FLUX Dev workflow with correct node types

Browse Source 
- Replace CheckpointLoaderSimple with UNETLoader
- Replace CLIPTextEncode with DualCLIPLoader + CLIPTextEncodeFlux
- Add VAELoader with pixel_space
- Remove negative prompt (FLUX uses guidance differently)
- Set CFG to 1.0, guidance in text encoder (3.5)
- Add all node connections in links array
