Pull request overview

This pull request refactors observer-triggered Microsoft 365 group/team membership synchronization from synchronous inline operations to asynchronous ad-hoc tasks. When Moodle events fire (user enrollment updates, role assignments/unassignments, enrollment instance updates), instead of immediately calling the Microsoft Graph API to sync the user's role in the connected Microsoft 365 group, the code now queues lightweight ad-hoc tasks that execute later.

Changes:

• Created new ad-hoc task class usergroupmembershipsync that encapsulates single user-course sync logic
• Updated four observer methods to queue ad-hoc tasks instead of performing synchronous API calls
• Added language string for the new task
