# /fp/wo/<id> — scan-redirect endpoint.
#
# The WO box sticker embeds a QR code that encodes this URL. When
# warehouse staff scan the sticker with their phone / tablet /
# handheld scanner, the device opens the URL; this controller then
# redirects them to the work-order form inside Odoo's backend.
# Logged-out users land on the standard Odoo login page and bounce
# back after authenticating (Odoo's redirect handles the round-trip).

             the WO id rather than the MO id)
