Phase 5: Photo Pre-Editor (Filerobot)

- Added react-filerobot-image-editor dependency
- PhotoPreEditor component with full editing capabilities
- Crop, filters, adjustments, annotations, watermark tabs
- Opens after image upload, before adding to canvas
- Exports edited image as PNG for canvas use
