Python calibration tool: simplify graphs, fix CancelledError

- Remove orange "last shot peak" line (unreliable at 20Hz)
- Remove rolling max curve (not useful in practice)
- Add specific asyncio.CancelledError catch in ble_loop with retry
  message when device is already connected elsewhere
- Clean up titles: show only current val + threshold
