feat(configurator): blanket/block-partial flags + WO group + per-line missing indicator

Phase B partial landing (B1, B2, B3, B5):

- B1/B2: x_fc_is_blanket_order and x_fc_block_partial_shipments on
  sale.order; matching booleans on the wizard header.
- B3: x_fc_wo_group_tag Char on sale.order.line and wo_group_tag on
  wizard line. Free-text tag; bridge_mrp will batch lines sharing a
  tag into one MO in a follow-up.
- B5: is_missing_info computed Boolean on fp.direct.order.line;
  tree uses decoration-warning to highlight incomplete rows in amber.
