fix(sticker): wire SN # + Thickness to the correct Sub 5 fields

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).
