When validate_type selected a preferred_item from remaining_items
(e.g. the sole IfcBooleanResult in a representation), it left that
item in the list. The subsequent Items filter removed every item,
leaving Items=[] and causing guess_type to return
"MappedRepresentation" — silently corrupting the representation.
Also removes temporary debug print statements added during
investigation of the wall-to-slab extension workflow.

add_railing_representation now factors into two parts:
* compute_wall_mounted_handrail_geometry returns a pure-geometry
WallMountedHandrailGeometry dataclass (handrail polyline + support
list + terminal caps), no IFC mutation.
* add_railing_representation wraps that dataclass into an
IfcShapeRepresentation as before.
Downstream consumers that want the same math without round-tripping
through an IFC file (Blender gizmo previews, viewport drafts) now
drive compute_X directly. Future add_X_representation work in the
geometry API is encouraged to follow the same shape — a sibling
compute_X function + thin IFC wrapper.
The railing_type parameter is dropped from the signature — only
WALL_MOUNTED_HANDRAIL was ever supported, so the kwarg was dead.
The Bonsai railing-modifier caller is updated in the same commit
to stop passing it; without that update Bonsai's
finish_editing_railing_path raises TypeError on the first edit.
RailingSupport and WallMountedHandrailGeometry use @dataclass(slots=True)
— they're constructed N-per-cap during arc sampling, so the per-instance
overhead matters.
Public symbols (RailingSupport, TERMINAL_TYPE,
WallMountedHandrailGeometry, compute_wall_mounted_handrail_geometry,
add_railing_representation) re-exported from ifcopenshell.api.geometry.
New test/api/geometry/test_add_railing_representation.py covers the
compute/wrap contract.

Drops the module-local ``mm()`` helper in favour of the centralised
``ifcopenshell.util.unit.mm_to_m`` (added earlier in this PR). The
``as mm`` import alias preserves the existing call sites' readability.

IfcRelConnectsPathElements has an optional ConnectionGeometry attribute for
recording the geometric cut-plane between adjacent elements, but there was
no way to set it via the API.

assign_product creates IfcRelAssignsToProduct linking a structural member to
a physical building element. assign_to_building creates IfcRelServicesBuildings
linking a structural analysis model to a building. add_topology_representation
creates IfcTopologyRepresentation for structural elements, inferring the
representation type from the item class.

add_boolean was removing second operands from ALL IfcShapeRepresentations
that referenced them, which could corrupt unrelated shapes and leave
representations with empty Items (bug #7803).
The API no longer modifies Items — callers manage this explicitly.
validate_type and Bonsai's AddBoolean operator now handle their own
item removal scoped to the correct representation.

- Add dual-rotation support for AXIS3 slabs (IFC angle + object rotation)
- Fix profile editing to display horizontal projection for tilted slabs
- Fix AXIS2 layer slicing to use local extrusion direction for walls
- Fix ChangeExtrusionDepth to refresh geometry after depth changes
- Remove rotation lock on slabs to allow free rotation
- Fix undefined variable bug in add_slab_representation.py
The issue happens when a wall has a "ATPATH" connection and has a
negative direction sense. It mixes the profile points in an incorrect
order. This commit seems to fix it, but maybe there is a better solution.
In some cases remove_representation got 2x times faster (when there were a lot representation items that are not IfcTessellatedFaceSets).
getattr with attribute that might not be present on the element could be much slower then checking it's class explicitly.
If user has fake-bpy-module for type hints, it will fail with `ImportError: cannot import name 'Vector' from 'mathutils' (unknown location)` instead of `ModuleNotFoundError`.
