Fix ci-bonsai-daily: renumber stale STEP ids in BDD feature fixtures

Several BDD scenarios hardcode absolute representation-item object names
whose trailing number is the IFC STEP line id
(f"Item/{item.is_a()}/{item.id()}"). Those ids drift when file-creation
order changes; a recent shift moved all of them by a uniform -4, so the
scenarios failed with "Item/.../NN does not exist".

The failing step (the_object_name_exists in test_feature.py) dumps the
full bpy.data.objects listing on failure, so the correct current ids are
recoverable directly from the CI log (run 29208793599, tested commit
36e21e882f, an ancestor of HEAD with only a .gitignore commit between).
Renumber to match:
  IfcExtrudedAreaSolid/77->73, IfcPolygonalFaceSet/76->72,
  IfcVertexPoint/69->65, IfcEdge/72->68, IfcFace/74->70.

Verified against the CI failure dump (a local build produces different
ids, so this is validated by CI's own object listing rather than a local
run). boolean.feature also hardcodes IfcHalfSpaceSolid/90 and panel text
[91] downstream of the failing assertion, which CI never reached and so
never dumped; left as-is to avoid guessing - they will print a fresh dump
next run for a follow-up if still stale.

This change was made with the assistance of an AI tool.
