Rotating an ArchSectionPlane object caused its cutting effect to flip,
affecting both the live `CutView` and 2D projections. The
`_SectionPlane.execute()` method incorrectly tried to auto-correct the
orientation of a temporary plane before applying the object's final
placement. The fix refactors this to a "transform-then-verify" pattern:
the object's full `Placement` is now applied to the temporary plane
first, and only then is the resulting face's actual normal validated
against the intended normal from the `Placement`. This ensures the
`Shape` is always geometrically consistent with the `Placement`, making
the cut direction predictable at all angles.
Fixes#21364.
`self.Type` should be set in `__init__` and `loads`, and not in `onDocumentRestored`.
Additionally:
fixed mistake in `loads` in ifc_objects.py.
Fixes: #7387.

PR to change the base object of BezCurve, BSpline and Wire to `Part::FeaturePython`. This will only affect new objects. So code will have to also keep handling the old object type (`Part::Part2DObjectPython`).
The modification of BimPreflight.py needs to be verified. The steps in the old code lacked logic IMO. But I may have misunderstood.
