Add form-based PUT update tests via define_form_update_tests macro for all
7 entities. Add hand-written datastar update tests for roasters, roasts,
cafes, brews, and cups. Add brew/cup update API tests (CRUD + auth).
Add put_form, put_form_datastar, create_default_brew, create_default_cup
test helpers.
Drop the rating column from cups. This removes the field from the
domain model, repository, API routes (including the PUT/update
endpoint), CLI, and all related tests.
- Test CRUD operations: create, list, get, update, delete
- Test auth requirement, optional fields, enriched data
- Test validation: no changes returns 400, nonexistent returns 404
