feat(sticker): much bigger text + QR +30%

wkhtmltopdf renders CSS font-size at a smaller physical scale
than the em-square math predicts (a "30pt" cell text was only
~4mm tall visually). Pushing all type up significantly so it
actually reads at scan/print distance:

Text bumps:
- Body field text 30pt -> 50pt (+67%, label + value)
- WO# 56pt -> 72pt (+29%)
- Notes label 30pt -> 44pt
- Notes content 22pt -> 30pt (+36%)
- Muted rev tag 22pt -> 30pt
- Body cell padding 0 10px -> 0 8px (a touch more horizontal
  room for long values now that the font is bigger)

QR + 30% as asked:
- Wrapper 280 -> 365px (+30.4%). Image 368 -> 480px, offset
  -44 -> -58px (recomputed for the new quiet-zone crop).

Header re-balanced for the bigger content:
- Height 25% -> 32% (fits the +30% QR + bigger WO# + bigger
  logo at 135px)
- Body band: 75% -> 68% (rows now ~9.6mm tall; line-height
  1.0 keeps the 50pt body text snug inside)
