Initialize the effective source and singular field for the gravitational self-force problem in a regularized region around the puncture. Replaces 'elliptic::Actions::InitializeFixedSources' in the standard elliptic initialization.
The regularized region is chosen as the full block containing the puncture. In this region, the Tags::FieldIsRegularized is set to true and the effective source and the singular field are set by the GrSelfForce::AnalyticData::CircularOrbit class. Outside this region, the fixed source and singular field are set to zero.
