feat: PreloadsInterferometer passes mesh-geometry fields through

Completes the D5 cross-dataset-type contract (PyAutoLens#599): an interferometer lead factor
in a joint imaging+interferometer graph can now carry the shared source-plane mesh alongside
its channel-invariant curvature matrix + mapper.
