Refactor super module: Move HTTP handlers to new super/v1 package

- Deleted old super.go file and moved all related HTTP handlers to new package structure under backend/app/http/super/v1.
- Updated service imports in super.go and super_test.go to reflect new DTO paths.
- Created new auth, contents, orders, tenants, and users handlers with corresponding routes and methods.
- Added new DTO definitions for authentication and content management in the super/v1/dto directory.
- Implemented new migration for content_access table and created model for it.
