RotationParameters was a moving-average store (profile_radius, beam_x, beam_y,
mosaicity) held by IndexAndRefine but never read or written - none of its four
accessors had any call site. Remove the class, its member, the include, and the
CMake entries.
Also set retain_outcomes=false for the online receiver's IndexAndRefine: online
scaling/merge at the end of a run is not enabled yet, so the whole-run
integration_outcome is unused there. Revert to true when online scaling lands.
