feat(receiving): technicians can count+close receivings from the tablet

ACL: grant group_fp_technician write+create on fp.receiving / line / damage.
sudo the internal sale.order x_fc_receiving_status write so a non-privileged
technician isn't blocked inside action_mark_counted / action_close.

Tests deferred to entech (local Docker unavailable this session).
