1. Fix vi.mock factory: importOriginal -> db.and/eq/exists/or stubs
(removes ReferenceError from undeclared imports in test)
2. Remove MedicalAlert.id — not in schema/migration/DB, only in types
3. Replace z.string().max(100) coatType with z.enum for CoatType union
4. Fix test expecting coatType "smooth" (invalid) -> "double" (valid)
5. Add TC-API-3.8 through TC-API-3.15 to UAT_PLAYBOOK.md §4.3
