/**
 * Trait DatabaseTestCase
 *
 * A trait for tests that need database access but should use an isolated
 * SQLite in-memory database instead of the real database.
 *
 * This trait:
 * - Ensures the test uses an in-memory SQLite database
 * - Runs migrations for clean test state
 * - Prevents tests from affecting production data
 *
 * Usage:
 *   use Tests\Support\DatabaseTestCase;
 *
 *   class MyTest extends TestCase
 *   {
 *       use DatabaseTestCase;
 *       // ...
 *   }
