Add content-based hashing to recipe images for proper cache invalidation while maintaining graceful degradation through dual file storage. Changes: - Add imageHash utility with SHA-256 content hashing (8-char) - Update Recipe model to store hashed filenames in images[0].mediapath - Modify image upload endpoint to save both hashed and unhashed versions - Update frontend components to use images[0].mediapath with fallback - Add migration endpoint to hash existing images (production-only) - Update image delete/rename endpoints to handle both file versions Images are now stored as: - recipe.a1b2c3d4.webp (hashed, cached forever) - recipe.webp (unhashed, graceful degradation fallback) Database stores hashed filename for cache busting, while unhashed version remains on disk for backward compatibility and manual uploads.

# Image Hash Migration Script
|
|
# This script triggers the image hash migration endpoint in production
|
|
# It will:
|
|
# 1. Find all images without hashes (shortname.webp)
|
|
# 2. Generate content hashes for them
|
|
# 3. Rename them to shortname.{hash}.webp
|
|
# 4. Update the database
