Critical fixes:
1. Modal now applies rotation and crop to image, returns processed blob
2. Frontend sends processed image to backend (not original)
3. Zoom slider min/max now calculated based on image size
4. Initial zoom shows entire image in canvas
5. Zoom constraints prevent over-zooming or under-zooming
User experience improved:
- Sees full item at start (auto-fit zoom)
- Can adjust rotation/crop smoothly
- Adjusted image is what gets saved (not original)
- Zoom slider works correctly for any image size

Fixes issue where image was too small to see full item in modal canvas.
Changes:
- Calculate initial zoom to fit entire image in 800x600 canvas
- Don't zoom in (only zoom out to fit), preserving image clarity
- Reset button also resets to fit zoom instead of always 1.0
This ensures users can see the full item from the start and understand
what they're adjusting.
