Visual styling issues

[meessour]

1. "wmi." should not be at the start of the monitor names, maybe even add an option to enter a custom name.
2. The Corners don't have the light gray-ish border color, has to do with applied border radius.
3. In my opinion the font should look the same as Windows 11's time/date font, this might be Segoe UI.
4. There should be less spacing on the bottom or more spacing at the top.
5. There is a delay on the brightness percentage when changing slider, I believe the sliders' amount should always be synchronised with the number to the right.
6. The dotted border around the focused slider should be changed or removed, it is not in line with Windows 11's styling
