🚸(frontend) disable device controls when user lacks room permissions

Update user experience by clearly marking device toggle and control
components as disabled when users have insufficient room permissions.

Prevents confusion by providing visual feedback that device controls are
unavailable, improving clarity about what  actions users can perform
in their current role.
