Rebranded the auth_userkey plugin to auth_jwt, including changes to namespace, class names, and configuration settings to reflect the new jwt-based authentication mechanism. Updated copyright notices and contact information accordingly. This refactoring also includes the introduction of JWT token management using the Firebase JWT library, replacing the user quick keys.
This function forces users who try to access Moodle directly to be redirected to the "SSO Host". The functionality is enabled by setting a SSO redirect URl in the plugins admin settings
The forced redirect can be overridden by using the query param "enrolkey_skipsso=on"
