Feature Request: Display Per-Session Download/Upload Statistics

Issue Description

Currently, Tixati does not display download (DL) and upload (UL) statistics for the *current session*. Only lifetime totals are shown in the bytes counter. This makes it impossible to track data usage within a single session, which is critical for users on metered connections with Fair Usage Policy (FUP) limits.

Use Case

On FUP-limited connections, users need to monitor exactly how much data (in GB) has been transferred *during the current Tixati session*. The lifetime counter is insufficient, especially when Tixati runs in the background—users often close the application without noting session-specific usage.

Requested Feature  

Please add per-session DL/UL statistics (in GB, reset on application close/restart), displayed prominently, such as:  
- In the status bar (similar to Tribler's, qBittorrent’s bottom bar), or  
- In a dedicated Statistics tab (similar to BiglyBT).  

This small addition would greatly benefit users managing data caps under FUP restrictions.

Thank you for considering this improvement.

Please, look into this. I love Tixati but I cannot help myself being inside a metered FUP connection. It will be of immense help for someone like us.

The Dev is working on adding this. It may not be in the next release but it is coming.
