Subject: [PATCH] Add multi-adapter test support: SQLite + MySQL via Gitea
 Actions and rake task

- .gitea/workflows/test.yml: two parallel CI jobs (SQLite and MySQL),
  each generates its own database.yml inline and runs the test suite
- lib/tasks/test_multi_db.rake: `rails test:all_adapters` runs both
  adapters sequentially using DATABASE_URL to switch at runtime
