fix(tests): adapt permission tests to new RBAC architecture

- Add Role records for editor, viewer, guest in seed_full_data
- Link UserTenant.role_id to Role records (legacy string roles no longer grant permissions)
- Fixes 10 test failures caused by removal of Legacy Role Bypass
- All 33 tests now pass
