feat(sticker): 3-cell header + right-side Notes column + new field list

Restores the original ENTECH sticker layout from the operator's
screenshot reference:

Header (3 horizontal cells, divided by vertical rules):
  [Logo]  |  WO #WO-30019  |  [QR]

Body (left side = field table, right side = Notes column):
  PO #:        587854         | Notes:
  SN #:        -              | <customer-facing description>
  Customer:    ABC Manufact.  |
  Part #:      9876... Rev A  |
  Due Date:    May 17, 2026   |
  Thickness:   -              |
  Qty:         1              |

Changes from previous (stacked-left) layout:
- Header: 1-row 3-cell (Logo 28% | WO# 44% | QR 28%) replaces
  the 2-cell w/ logo+WO# stacked on left.
- Body: 2-region (66% / 34%) replaces single 7-row table.
  Notes column now spans full body height on the right.
- Fields: SN # and Thickness added; Process row removed.
- Labels: "PO (RO)" -> "PO #", "Part Number" -> "Part #".
- Notes content: switched from SO.x_fc_internal_note to the SO
  line's `name` (= customer-facing description per Sub 2 Q6).
- SN # reads _line.x_fc_serial_number (Sub 5 field).
- Thickness reads _line.x_fc_thickness with coating.thickness
  fallback (Sub 5 field, defensive 'in _fields' check).
