## Summary by CodeRabbit

* **New Features**
* Enhanced Android peer details with latency, data transfer totals,
connection timestamps, handshake information, relay and security status,
and ICE connection details.
* Added formatted latency values to support clearer connection-quality
indicators.
* **Bug Fixes**
* Peer lists now refresh WireGuard statistics before displaying transfer
and handshake information, ensuring current values are shown.
