The QR <img> src used `% quote(_scan_url)` to URL-encode the value,
but `quote` isn't always in the QWeb render context — particularly
on the fusion_pdf_preview / account render chains. Result:
KeyError: 'quote' when printing from the browser.
_scan_url is always base_url + '/fp/wo/<int>' — no characters that
need encoding. Replaced the % + quote() formatting with simple
string concatenation, dropping the quote dependency entirely.
Smoke verified on entech: MO + WO stickers render cleanly at 27KB
each (with QR image included).
