feat(reports): WO box sticker + QR-scan-to-WO endpoint

Client is migrating from Steelhead and needs to keep the small
parts-box sticker format the warehouse crew already knows. Two
pieces shipped together so scanning is seamless from day one:

1. report_fp_wo_sticker — 4x3" QWeb label bound to mrp.workorder.
   Layout mirrors the Steelhead sticker:
     * ENTECH logo top-left (via env.company.logo)
     * QR code top-right encoding /fp/wo/<id>
     * Grid: PO (RO) / Customer / Process / Part Number / Due
       Date / Qty / Notes
   Dedicated paperformat_fp_wo_sticker at 102x76mm, 300 DPI,
   landscape, 3mm margins — sized for thermal / inkjet label
   printers without shrink-to-fit.
   Binding added so "Print → WO Box Sticker" appears on every
   mrp.workorder record.

2. FpWoScanController — GET /fp/wo/<int:wo_id> redirects the
   scanner straight to the work-order form
   (/odoo/action-mrp.action_mrp_workorder/<id>). auth='user' so
   logged-in scanners land on the WO immediately; others bounce
   through Odoo's login and return to the same URL. No custom
   client work needed — any phone camera, handheld barcode
   scanner, or tablet browser opens the URL on scan.

Process row resolution chain: part.default_process_id →
coating.recipe_id → fallback. So the sticker prints whichever
process is actually going to drive WO generation for this line,
matching the direct-order wizard's Effective Process column.
