Hardcoded colors

[SzBeni2003]

While the most components are using colors that can be set on the styling admin panel, there still are several exceptions.
I have noticed two instances while setting up Gólyakörte Web: the cards on the communityList page are using a hardcoded value, and the other annoying component was the communities' web page link, which also uses a hardcoded default value, which can only be overridden by setting the communities' brandColor individually.

A note to this that might be related: on the communityList page, every logo is the "light mode variant", but the background itself is pretty dark, which makes some logos lose details
