Add tests for movie-directors admin route

[juzaweb]

Added a new test file tests/Feature/DirectorTest.php to cover the Route::admin('movie-directors', DirectorController::class) route.
The tests verify:

• Admin routes exist and are accessible to authenticated admins.
• Index and Create pages load successfully.
• Store action creates a new director record in the database.
• Edit page loads for an existing director.
• Update action modifies the director record.
• Bulk delete action removes the director record.
