fix(sticker): bigger QR + larger body text + tighter Notes row

- QR generation bumped from 300x300 to 600x600 (down-scales at print
  time instead of up-scales — eliminates the pixelation that broke
  thermal-printer scans).
- QR display wrapper grew from 380->460px; the underlying image and
  quiet-zone crop scaled proportionally (510->620px image, offset
  -65->-80px).
- Header band 40%->44% so the bigger QR has room without crowding
  the logo / WO# stack.
- Body band 60%->56%. First 6 rows take 15% of the band each (~9.4mm
  printed — slightly taller than the prior equal-split 8.7mm despite
  the smaller band) and the Notes row drops to 10% (~6mm). Notes is
  usually one-line content on these stickers; main rows carry the
  PO / Customer / Process / Part / Due / Qty info that has to read
  well from across the shop.
- Body font 38pt->44pt, muted 28pt->32pt. Notes row uses 32pt so 1-2
  lines still fit in its trimmed height.

Verified: 123,668-byte PDF renders cleanly on entech (WO-30019).
