- _compute_area_kind: name-based override so de-rack/de-mask steps land in the
De-Racking column and bake/oven steps in Baking, regardless of a mis-tagged
recipe kind (fixed WO cards scattering into the wrong shop-floor columns).
- fp.rack.load jobs extension: racking-step resolution by area_kind (not the
corrupt kind), equal-split/override ops, fp.job qty_racked/unracked rollups,
and independent rack movement (per-line moves) + de-racking unrack.
