Tracker: Tell pose view on Desktop to update its colors and replicant colors

... on B_RESTORE_BACKGROUND_IMAGE (which sets the Desktop color or wallpaper).

Remove kRestoreBackgroundImage, preferring the B_ version we got from
Backgrounds (and represents the same constant). Tracker already imported
this constant long ago.

Fixes #20028.
