Strengthens implementation of station_to_string. Adds alignment name …

…to stationing referent.

fixes to sequence.create_baseline:

- assert isinstance(res, list) was wrong because duplicate_task returns a tuple not a list
- removed overkill assertion anyway as the usecase is already typed.
- setting optional name or reuse planned schedule name
- usecase now returns created baseline work schedule

Fix #9278. calculate_unit_scale raises the SI prefix to the length ex…

…ponent for prefixed SQUARE_METRE/CUBIC_METRE units.

An SI prefix attaches to the base unit symbol and the prefixed symbol is
raised to the power as a whole: DECI CUBIC_METRE is dm3 = a litre = 1e-3 m3,
not 0.1 m3. The scale factor previously applied the prefix multiplier
linearly for all IfcSIUnits, inflating volumes x100 and areas x10 for such
declarations (produced e.g. by MagiCAD for Revit MEP exports).

Following the reviewer note in #9278, the exponent is taken from the
derived attribute IfcSIUnit.Dimensions rather than from substring matching
on the unit name: the multiplier is raised to LengthExponent only when the
unit's dimensions are a pure power of length, so prefixed derived units
(KILO PASCAL, MEGA NEWTON) and non-length units (KILO GRAM) correctly keep
the linear multiplier. This matches the exponent handling already present
in convert() and named_dimensions in the same module.

Adds regression tests for prefixed AREAUNIT/VOLUMEUNIT and for the
linear-prefix behaviour of PRESSUREUNIT/MASSUNIT.

Revised update_alignment_parameter_segment_tags to make EndTag optional

Adds update_alignment_parameter_segment_tags function

Updates update_key_point_referents to confirm to CT 4.1.4.4.3
