- Create tags table in schema with id, name (unique), createdAt
- Generate migration for tags table
- Create tag.service.ts with getAllTags (id+name, alphabetical order)
- Create tags.ts route with GET / handler
- Register /api/global-items and /api/tags routes in index.ts
- Add auth skip for GET /api/tags and GET /api/global-items
