feat(fusion_plating_jobs): external sticker — QR fills full width when no MASK/BAKE tags

Taller QR row (30->36mm) and the QR now expands to a full-width centered ~34mm
when a job has neither masking nor baking (was leaving the right half empty);
when tags are present, QR ~32mm on the left with MASK/BAKE stacked on the right.
Logo/WO-band/field rows trimmed to fund the bigger QR. Verified live (WO-30072
no-tags full QR; WO-30090 BAKE tag).
