Issues with new stylesheet

[BreakPoints]

I appreciate the theme being updated to better support qBittorent v4.5 but I've spotted a number of regressions/oversights. Edit: Forgot to mention I'm on Windows 11, Qt5

• Buttons no longer have a background so are not clear that they are buttons, for example see the OK button in the update dialog in the screenshot.
• Backgrounds for tabs, such as in the about dialog, look out of place.
• Links, as seen in the about dialog, are too saturated to be easily readable.
• Mouse over highlighting of text darkens enough to become harder to read.
• Personal opinion: the new scroll bars are rather ugly and do not indicate that they are scroll bars (missing up down arrows as they were before).
• Personal opinion: The square download bars are also rather ugly and don't fit the rounded icon design in the rest of the UI.
