Add filter for rest_api_can_edit_user_and_update_two_factor_options

[gutobenn]

What?

Introduce a new filter hook in the Two_Factor_Core::rest_api_can_edit_user_and_update_two_factor_options method.

Why?

To allow developers to programmatically control whether REST API endpoints related to Two-Factor authentication can edit a specific user’s settings.

How?

Added a new filter, two_factor_rest_api_can_edit_user, which allows overriding the default behavior by modifying the return value of the rest_api_can_edit_user_and_update_two_factor_options method.

Testing Instructions

The following snippet disables Two-Factor-related REST API endpoints (rest_setup_totp, rest_delete_totp, and rest_generate_codes) for a specific user (user ID 123):

add_filter( 'two_factor_rest_api_can_edit_user', function( $can_edit, $user_id ) {
    if ( $user_id === 123 ) {
        return false;
    }

    return $can_edit;
}, 10, 2 );

Testing Instructions

1. Apply the above filter to your codebase.
2. Attempt to call the Two-Factor-related REST API endpoints for user ID 123.
3. Confirm that the calls are blocked.
4. Ensure the endpoints continue to work for other users.

Changelog Entry

Added - New two_factor_rest_api_can_edit_user filter to control edit permissions via the REST API for specific users

This is great, thanks for your contribution @gutobenn!

Let me know if you don't have the capacity to document the filter and we can address that in a follow-up pull request.
