Add a typed setter to the existing RimcFractureTemplate_setScaleFactors
object method and let RicfScaleFractureTemplate forward to it via
RicfForwarding::findFractureTemplate(). Make RimFractureTemplate::m_id
scriptable (read-only) so templates can be looked up by id from Python.
Project.scale_fracture_template(template_id=...) in Python now resolves
the template object and calls FractureTemplate.set_scale_factors(),
emitting a DeprecationWarning.
