Implements Redis caching layer for recipe endpoints to reduce MongoDB load and improve response times:
- Install ioredis for Redis client with TypeScript support
- Create cache.ts with namespaced keys (homepage: prefix) to avoid conflicts with other Redis applications
- Add caching to recipe query endpoints (all_brief, by tag, in_season) with 1-hour TTL
- Implement automatic cache invalidation on recipe create/edit/delete operations
- Cache recipes before randomization to maximize cache reuse while maintaining random order per request
- Add graceful fallback to MongoDB if Redis is unavailable
- Update .env.example with Redis configuration (REDIS_HOST, REDIS_PORT)

Add comprehensive base recipe system allowing recipes to reference other recipes dynamically. References can include custom items before/after the base recipe content and render as unified lists.
Features:
- Mark recipes as base recipes with isBaseRecipe flag
- Insert base recipe references at any position in ingredients/instructions
- Add custom items before/after referenced content (itemsBefore/itemsAfter, stepsBefore/stepsAfter)
- Combined rendering displays all items in single unified lists
- Full edit/remove functionality for additional items with modal reuse
- Empty item validation prevents accidental blank entries
- HTML rendering in section titles for proper <wbr> and ­ support
- Reference links in section headings with multiplier preservation
- Subtle hover effects (2% scale) on add buttons
- Translation support for all reference fields
- Deletion handling expands references before removing base recipes
Fixes critical bug where recipes could not be deleted properly. The delete function had an early return statement that prevented database deletion from executing, leaving orphaned entries. Additionally, deleted recipes were not removed from users' favorites lists.
Changes:
- Remove premature return statement blocking database deletion
- Fix malformed fetch call structure (headers were inside body JSON)
- Add UserFavorites cleanup to remove deleted recipes from all users' favorites
- Ensure complete cleanup: database entry, image files (hashed and unhashed), and favorites references
- Replace connect/disconnect pattern with persistent connection pool
- Add explicit database initialization on server startup
- Remove all dbDisconnect() calls from API endpoints to prevent race conditions
- Fix MongoNotConnectedError when scheduler runs concurrently with API requests
- Add connection pooling with proper MongoDB driver options
- Add safety check for recipes array in favorites utility
