[Feature]: Show battery level on tray icon

Pre-flight checklist

• I searched existing issues and the Roadmap, and this isn't already tracked.

Problem / motivation

In the offical G Hub driver, users can quickly see their mouse's battery level in context menu, like the screenshot below:

However, now I can't find the same or similar feature in OpenLogi.

Proposed solution

If it possible, I hope OpenLogi's tray icon can provide the same feature, show my battery level and predicted using time (if possible) in tray icon. Maybe not show a progress bar but show one line of text like PRO Wireless: 50%, or PRO Wireless 50%, eta:x hr xx min

If needed, I can help to test and write some parts of this feature on Windows. Thanks to consider.

Alternatives considered

I've considered some way to this feature, including but not limited to below:

• Show a battery percentage number on tray icon's right button menu like the offical G Hub driver
• Show battery percentage as icon on tray icon
• Show a level bar as icon on tray icon
• Show level text in context menu

Below is some inspiration I drew in Figma that you can reference:
