Subject: [PATCH] Redesign profile photo upload with circular crop UI,
 server-side processing, and form integration

- Replace square preview with 280x280 circular container with crop ring overlay
- Zoom slider and drag-to-pan for precise crop positioning
- Client-side crop via canvas at 400x400 output resolution
- Server-side resize to 400x400 (LANCZOS), EXIF stripping, RGB conversion, JPEG optimization
- Generate CSRF token in before_request so photo upload fetch works
- Save button now also submits the profile form (photo + fields updated together)
- Remove dead photo-upload-form handler and unused CSS
- Clean up debug markers and attendee code field from profile page
