All custom flag and card state colors displaying black in browse window

[madglass]

Problem description

*Regardless of the color selected, the flag icons and their corresponding flag "highlight" are black in browse. The card state "swatch" has the same issue. Problem seems to be limited to the browse window; colors display properly on main screen and during review. It's occurring on both my desktop and laptop.

However, if using a default theme (Catppuccin, Nord, etc.) the card states and flag colors/highlights display properly in browse.

Attached screenshot is the result of attempting to change the red flag and "new" card state to a custom color.*

The issue is that the colours listed in backend_color_to_aqt_color are passed directly into QColor in adjusted_bg_color, which does not take RGBA hex nor the rgba(...) format

https://github.com/ankitects/anki/blob/039c7fc0a9cee81b975e6419d9be20aef338db8f/qt/aqt/browser/table/__init__.py#L125-L134

Though for some reason, according to https://doc.qt.io/qt-6/qcolor.html#fromString, it takes ARGB hex 🤔

A simple fix would be to strip the alpha away (or prepend it to form #ARGB) when anki_name is one of those colours in replace_color
