Administration: Update design of the Dashboard welcome panel.

Tone down the brightness of the dashboard panel by using a white background behind the main text, and use the highlight color from each color scheme for the main background. This also introduces a `$scheme-name` SCSS variable to allow overrides for specific color schemes.

Props critterverse, sabernhardt, joedolson, audrasjb.
See #54489.
