feat(sticker): restore older 3-cell-header + right-Notes-panel layout

Per user request — the previous (now restored) layout is the one
operators were used to:

- Header: single row with 3 cells side-by-side (Logo | WO # | QR)
  instead of the stacked logo+WO# left / QR right.
- Body: 3-col layout (Label | Value | Notes-rowspan). Notes is a tall
  right-side panel spanning all 7 body rows — gives operators ~62mm
  of vertical space for multi-line notes (vs. the prior single-row
  Notes that capped at ~8.7mm).
- Fields: PO #, SN #, Customer, Part #, Due Date, Thickness, Qty.
  SN # joins x_fc_serial_ids; Thickness composes from the coating's
  thickness_min/max + uom.
- Header band 32% (was 40%), body band 68% — the header is shorter
  because there's no stacked logo/WO# anymore; body grows to absorb
  the freed space, but the 7-row grid already provided ample
  per-row height.
- Body text 17pt main / 13pt muted (down from 38pt). The big-font
  pass was for a 7-row equal-height grid; with the 3-col layout
  the per-row height is unchanged but the rows are now narrower
  (only ~70% of the page width minus the Notes panel), so a more
  conservative font keeps text from wrapping mid-cell.
- QR generation stays at 600x600 (sharper print at scan time).

Variable interface unchanged. mrp.production / mrp.workorder /
fp.job / sale.order all still call the same inner template; two
new variables (_serial_names, _thickness_str) get pre-set by the
defaults template and resolved by the inner.

Verified: 72-KB PDF renders cleanly on entech for WO-30019.
