♻️(frontend) refactor permission updates to preserve admin privileges

Enhance participant permission update logic to only affect users
without room privileges, ensuring admins can maintain their microphone
and camera access during bulk permission changes.

Prevents accidental disruption of admin functionality when applying
permission restrictions to regular participants, maintaining proper
role-based access control hierarchy.
