Every overlay on a thumbnail now composes the shared THUMB_BADGE_* classes
(one shape, one height, one ring, three semantic colour variants: primary
for user state, neutral for metadata, pick for auto-suggested best). RAW
badges, BEST pill, Keep-this button and the dimensions chip — previously
three different styles — join the family, is_duplicate moves to neutral
since it's file metadata not a user decision, and the selection check
shrinks to match the rest.
