Create tags route

Implementation description

• Updated tags model to add a unique constraint to name
• Added create route
• Modified update route to catch non-unique name error

Steps to test

1. Upgrade database with latest migration: bash ./scripts/flask-db-upgrade.sh
2. In order to test these routes with Postman, first comment out @require_authorization_by_role({"Admin"})
on lines 47 and 71 of backend/app/rest/tags_routes.py.
3. Create: Create a tag by POSTing to /tags/ (e.g. {"name": “Cool Tag”, "status": "Active”}). This should show up in your database. Try creating another tag with the same name - you should get an error telling you that name already exists.
4. Update: Update tag by id by PUTing to /tags/[id] an updated tag (e.g. {"name": “Epic Tag”, "status": "Active”}). Database should show modified tag. Try updating a different tag to have the same name - you should get an error telling you that name already exists. Also try updating a non-existent id - you should get an error telling you that id was not found.

LGTMMMMM, using the DB to handle the duplication logic is so much nicer, great work on getting that to work!! 👨‍🍳

LGTM! Tested creating and updating duplicate tags on postman and they both returned errors as expected
