Add Redis caching for lookup data and admin cache management
- Add lookup-specific cache keys and methods to CacheService - Add cache refresh on lookup CRUD operations in AdminLookupHandler - Add Redis caching after seed-lookups in AdminSettingsHandler - Add ETag generation for seeded data to support client-side caching - Update task template handler with cache invalidation - Fix route for clear-cache endpoint 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
