feat(46-03): update GenerateImageNode to remove inline parameters (full-bleed prep)

- Removed aspect ratio, resolution, and search toggles from node body
- Removed ModelParameters component from node body
- Parameters will be shown in ControlPanel (Plan 02 integration)
- Image preview now has room to fill node in full-bleed pattern

Task 1 partial progress: GenerateImageNode parameters removed, 24 more nodes need header props removed and full-bleed content applied
