feat(numbering): WO grouping by recipe + parent-derived bulk naming

Replaces x_fc_wo_group_tag grouping with resolved-recipe grouping.
Bare WO-<parent> when 1 recipe, WO-<parent>-NN zero-padded for N>1
ordered by min line sequence. fp.job inherits parent-numbered mixin
for the manual-add path; bulk SO-confirm sets names explicitly.
