Sort sessions by most recent - ended sessions by terminated time, active by created time

- Ended sessions now sorted by terminatedAt timestamp (newest first)
- Active sessions sorted by created timestamp (newest first)
- Makes it easier to find recent sessions in the dashboard
- Falls back to created time if terminatedAt is missing
