fix(desktop): drop panel tint, cap info tooltip width

Inputs use the app-wide desktop-input-chrome CSS (background set directly,
utilities lose the cascade), so the tinted panel surface was what made them
read flat — remove the tint and let the accent border + row hairlines carry
the structure, matching how inputs sit everywhere else in settings. The Tip
primitive styles for 2-3 word labels (bold, no wrap cap); give the info
variant a width cap, normal weight, and snug leading.
