- Refactored `CreateAdmin` form to utilize a new `PhoneNumberInput` component with validation rules.
- Updated `useCreateAdminPresenter` to normalize phone number input before submission.
- Enhanced error messages for phone validation in `Texts` constant.
- Modified `User` schema to validate phone numbers using E.164 format.
