fix(fusion_plating_jobs): HD QR on job stickers (300x300 -> 1000x1000)

All three barcode_data_uri('QR', ...) calls bumped from 300px to 1000px
(under Odoo's 1.2M-pixel barcode cap, per rule 14). At the ~34mm display
size that's ~750 dpi — crisp on the label printer. Verified: PDF now embeds
a 1000x1000 QR XObject.
