Function PollsSession

PollsSession(__namedParameters?: PollsSessionProps): Element
PollsSession - Complete polls session management component

Wraps PollsWindow with session management including:
- Empty state with file list of saved sessions (owner-only create button)
- Session header with close button
- PollCreator dialog for creating new polls
- Automatic file loading from S3
- Auto-save integration (owner only)
This is the recommended component for sidebar integration as it handles all session lifecycle management internally.

```
// In Sidebar.tsx
case 'polls':
  return <PollsSession />;

  }}
  pollsWindowProps={{

  }}
/>
