Gorgious56 c7d5d6c498 Gate slab disconnect gizmos behind parametric edit lifecycle
Wires slabs into the parametric edit framework (tool.Parametric
.EDIT_TYPES) so the wall-slab disconnect UI gets ESC handling, red
cancel icon, mutual exclusion with other parametric edits, and
per-feature gizmo prefs — all from BaseParametricGizmoGroup — without
duplicating the lifecycle.

Adds:
- ParametricObject("slab") registry entry + tool.Parametric.is_slab
  predicate (any IfcSlab).
- BIMSlabProperties with is_editing flag; PointerProperty wired by
  the framework's register_object_properties.
- bim.enable_editing_slab / bim.finish_editing_slab /
  bim.cancel_editing_slab operators on tool.Ifc.Operator so they
  flow through tool.Parametric.run_bim_op cleanly. No IFC mutation
  — slab edit is a pure UI gate; finish and cancel share the body.
- tool.Model.get_slab_props accessor.
- GizmoSlabEdition inheriting BaseParametricGizmoGroup with the
  pen / validate / cancel triad. is_element_type narrows to
  IfcSlab with at least one wall clipped to its underside.

The disconnect-icon group GizmoSlabUnjoinWalls polls behind
_slab_connection_gizmo_poll_gate(require_editing=True), which now
reads is_editing through tool.Model.get_slab_props.

Drops the standalone GizmoSlabConnectionAccess + the
setup_pen_cancel_icons helper added earlier in this branch — both
superseded by the framework integration.

Also folds in the wall + multi-slab gizmo polish requested live:
- Wall side: stack the per-slab unjoin icons vertically (up to 5)
  so multi-slab connections each get a distinct clickable icon;
  hover-highlight reveals which slab will disconnect.
- GizmoPairDisconnect activates when 2 elements with an
  IfcRelConnectsElements(TOP) rel are selected, with the icon at
  the wall-slab connection world anchor.
- Wall-slab anchor moved from slab clip Z to wall top +
  WALL_SLAB_CONNECTION_Z_CLEARANCE so the disconnect icon perches
  above the extend-vertical / slope gizmo instead of overlapping.
- Shared _resolve_active_partner_pair helper for 2-selection
  gizmos; _slab_connection_gizmo_poll_gate added to
  _REQUIRED_CALLEES + GizmoSlabEdition added to the AST
  forward-compat allowlist.

Build note: wall.py's DisconnectElements._perform imports
bonsai.core.connection.disconnect_rel — that core module is being
added in a parallel-session commit. Until that lands the addon
import will fail.
