- Create a new Blade view for domain registration (`registrant-tochuc.blade.php`) to capture organization and manager details.
- Implement email templates for new domain orders for both admin (`domain-order-new.blade.php`) and customers (`domain-order-received.blade.php`).
- Add CSV exports for client and domain data.
- Introduce tests for customer mass assignment, password reset, login throttling, and permission gating.
- Ensure service renewals use current pricing and validate ownership for virtual machines.
