fix: banner/avatar overlap in settings preview and refine profile color system

Move bg-surface-channel from info section to card wrapper in AccountPanel
so the avatar's negative margin overlaps into the banner correctly. Replace
accent color presets with 7×3 banner color palette, remove accent color
tinting from display names in popout/modal, and refactor gradient entries
to expose from/to hex stops.
