NISB BANIS: turn off per-crop relabel_connected_components

base_banis.yaml inherited relabel_connected_components: true, which
renumbered label IDs per crop but did NOT renumber label_aux. The
runtime skeleton_aware_edt path then did `skel_crop == instance_id`
with mismatched IDs, silently falling back to a plain boundary EDT —
disabling the skeleton signal that v2+/erosion2 set up.

Flip the default off in base_banis.yaml so v0/v1 still get stable IDs
and v2+ actually use their precomputed seg_skeleton caches. The schema
default (False) already matched this intent; only the explicit override
here was forcing the bug.
