[HaikuDepot] UI: Usages conditions view colours compatibility with dark schemes

[Starcrasher]

If I understand well, this is the import of an html text. You can make appear that view using "Connexion" or "View last usages conditions"

The view itself seems to always have a white background but the text is taking panel_text_colour. In case of dark schemes this colour is usually very light, making the text unreadable.

Since the idea is to have a separate view, document_background_colour and document_text_colour would do better but perhaps it is not possible. In this case, since the background is white, finding a way to force text to black could work.

Please retest after hrev58074

Tested on hrev58095 with both 32 bits and 64 bits. The background is now taking document_background_colour but the text is still using panel_text_colour. So, it is still a wrong pair of colours but, somehow it already works better most of the time.
