Issues with dark modes

[Klumbumbus]

This is a collection of issues with dark mode, especially with FlatLaf Dark, reported before on different places. The reason might be in JOSM core, the FlatLaf plugin or the FlatLaf Laf itself.

• The text in the status bar is nearly unreadable --> see 3rd screenshot in #19027 (​https://i.ibb.co/gRRkTWh/Snag-27628415.png)
  • Similar issue with info box message about new mails in the bottom left corner screenshot​.
• Blue links are hard to read --> ticket:19027#comment:24
• Boolean values with icons in menus are hard to see if checked or unchecked --> attachment:check_boxes_dark_mode.png​ (Windows LaF for comparison on the right, original reported in #19785)
• The warning message in the upload dialog looks not good (light orange background color) --> attachment:upload_dark_mode.png​ (original reported as ​facebook comment)
• General issue with too light background colors
  • skyper on #19027 comment 23:

    Think all background colors, except blue, of boxes like in relation manager and history viewer could be darker at least two of the three colors. Would prefer a darker red and yellow/orange leaving the green lighter for color-bind users (screenshot​).
