System Tray Visibility

[flowrean]

I am using Pomotroid v1.6.0 on Windows 11 (set up with both breaks and auto-start disabled). I find the visibility in the system tray to be bad compared to the legacy version (v0.13.0), both in light and dark system modes.

What I would expect: Session progress is clearly visible. When the session is complete, this is also clear from the system tray icon.

What happens:

1. When using Windows light mode, the session progress is hard to see because the 'empty' part of the circle is black and it doesn't have enough contrast with the red of the rest of the circle. Maybe drawing only the red part and leaving the rest of the circle transparent would be better? Or the circle could be made thicker, as it was in v0.13.0, for improved visibility?
2. When using Windows dark mode and the focus round is complete (no new round started yet, auto-start is disabled), Pomotroid basically creates what looks like an empty spot in the system tray, as the icon is now a black circle. In v0.13.0 there used to be a pause sign instead.
