feat(fusion_plating_jobs): internal sticker QR — bigger + quiet-zone crop (match external)

Applied the same QR treatment to the Internal (Layout A) header QR: bumped the
box to 30mm and added the ~10% quiet-zone crop wrapper so the pattern fills the
box (finders intact), centered via the table cell. HD (1000px) already applied.
Verified live (WO-30072).
