Loki gets lab-frame transform for solid angle from uncalibrated detector position

[SimonHeybrock]

See

esssans/src/ess/loki/general.py

Lines 86 to 90 in 9434614

	def detector_lab_frame_transform(
	detector: NeXusDetector[ScatteringRunType],
	transform_path: TransformationPath,
	) -> LabFrameTransform[ScatteringRunType]:
	return LabFrameTransform[ScatteringRunType](detector[transform_path])

I don't know if this was done correctly in the past and broken in some graph restructure, or if it was always wrong?

As this part of the NeXus workflow is currently being refactored in scipp/essreduce#114 I will fix it as part of those updates.
