feat: Implement required port validation for service applications

- Added `requiredPort` property to `ServiceApplicationView` to track the required port for services.
- Introduced modal confirmation for removing required ports, including methods to confirm or cancel the action.
- Enhanced `Service` model with `getRequiredPort` and `requiresPort` methods to retrieve port information from service templates.
- Implemented `extractPortFromUrl` method in `ServiceApplication` to extract port from FQDN URLs.
- Updated frontend views to display warnings when required ports are missing from domains.
- Created unit tests for service port validation and extraction logic, ensuring correct behavior for various scenarios.
- Added feature tests for Livewire component handling of domain submissions with required ports.
