feat(admin): replace image URL input with ImageUpload component + fetch-from-URL

Admin item edit page now uses the same ImageUpload component as the rest
of the app (file upload, preview, crop editor). Also adds a "Fetch from URL"
input that uses /api/images/from-url. Renames "Source URL" to "Product Page URL".

Backend updated to accept imageFilename, dominantColor, cropZoom/X/Y fields
and return presignedImageUrl for display.
