Filter mesh page task list to show only supervisor tasks

- Add `isSupervisor` filter to rootTasks filter in TaskList component
- Only supervisor tasks will appear in the mesh page task list
- Regular tasks are now hidden from the main view
- Update empty state messages to reflect supervisor-only filtering
- When clicking a supervisor task, its detail still shows orchestrated tasks
