Subject: [PATCH] Enforce behavior for AdvancedElectronicSignature

Added logic to enforce automatic enabling of Two-Factor Authentication (2FA) and access code usage when the `AdvancedElectronicSignature` certification type is selected.

- Added `@bind:after` event handler to `<select>` for `_certificationType` to handle changes.
- Introduced `IsFesSelected` property to check if `AdvancedElectronicSignature` is selected.
- Updated `OnTfaChanged` to enforce `_tfaEnabled` and `_useAccessCode` when `IsFesSelected`.
- Added `OnCertificationTypeChanged` method to reset validation and normalize settings.
- Updated `NormalizeSettings` to ensure `_tfaEnabled` and `_useAccessCode` are set appropriately.
- Called `NormalizeSettings` during component initialization to ensure consistent state.

These changes ensure the UI and logic reflect the enforced behavior for the `AdvancedElectronicSignature` certification type.
