Fix template regressions: missing Response return/import in controllers and middleware #498

Summary

Two regressions remain in module templates after the remove response param in templates work:

1. validateRequest() response is not returned in DemoWeb password middleware template.
2. CommentController in DemoWeb template uses : Response return types without importing Quantum\\Http\\Response.
3. Toolkit EmailsController::delete() calls redirect(...) without returning it, while method return type is Response.

Affected files

• src/Module/Templates/DemoWeb/src/Middlewares/Password.php.tpl
• src/Module/Templates/DemoWeb/src/Controllers/CommentController.php.tpl
• src/Module/Templates/Toolkit/src/Controllers/EmailsController.php.tpl

Expected

All template methods typed as Response should always return a Response, and Response type should be properly imported where used.

Proposed fix

• Return $errorResponse when validateRequest() fails.
• Add missing use Quantum\\Http\\Response; import.
• Return redirect(...) in EmailsController::delete().
