NumCosmoGalaxyShapeFactorprepare_data_array

Prepares the per-galaxy caches used by the integrand: lens geometry (projected radius, tangential-frame rotation of the observed ellipticity and calibration bias) and the reduced-shear optimization cache. Also prepares the population fragments and runs the subclass prepare hook.

Calls nc_galaxy_shape_factor_prepare() (which decides for itself, via its own cached hashes, whether the geometry/profile caches actually need recomputing), then loops over data_array applying nc_galaxy_shape_factor_update_data_radius()/_optzs()/_pop(). update_radius and update_optzs gate whether the radius/optzs steps run in that loop for every data_array entry; the population step always runs.
