refactor: services layer, valibot validation, shared CSS utilities, aria labels, and drizzle migrate

- Extract groceries/categories/references services with db injection
- Add valibot for form validation and safe numeric id parsing
- Fix category delete FK behavior with onDelete: set null + migration
- Replace custom migrate.js with drizzle-orm/libsql/migrator
- Add shared CSS utility classes in app.css (forms, lists, buttons)
- Add aria-pressed and aria-label on interactive elements
- Remove redundant app.css imports and unused /stores import
- Add integration tests for all services using drizzle migrate helper
- Remove smoke test; add db:migrate and db:studio scripts
