Subject: [PATCH] ui(duplicates): show grandparent + parent in path strip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When two duplicates live in folders with the same parent name (e.g.
matching '2023' subfolders under different archives), showing only
the parent gave both thumbnails the same label. Walk one level up:
the path strip now renders '…/<grandparent>/<parent>' so the user
can always tell two copies apart at a glance. Filename still
surfaces via the title tooltip.
