fix: Configure SQLite database for testing environment

- Add SQLite in-memory database configuration to phpunit.xml.dist
- Configure database connection in TestCase::getEnvironmentSetUp()
- Ensures ApiHealthCheck tests pass with prefer-lowest dependencies
- Fixes CI failures on GitHub Actions with Laravel 10.0.0

This fix ensures that health check tests have a proper database
connection even in minimal dependency environments (prefer-lowest).
The issue was only visible in CI with older Laravel versions.
