The values were structurally blank because the variable
resolution was reading the wrong field names:
Was: _line.x_fc_serial_number (doesn't exist)
_line.x_fc_thickness (doesn't exist)
Now: _line.x_fc_serial_id.name (M2O fp.serial)
_line.x_fc_thickness_id.display_name (M2O fp.coating.thickness)
Sub 5 shipped these as Many2one registries (fp.serial,
fp.coating.thickness) — the sticker was guessing at flat
Char-field equivalents that were never created.
Verified on SO-30019: SN # now prints "65767", Thickness now
prints "0.3-0.5 mils" (the en-dash in display_name mojibakes
to "â€"" through wkhtmltopdf's font path on entech, so we
replace en-dash + em-dash with ASCII hyphen-minus before
render — ASCII-only is what label printers want anyway).
