Pull request overview

This PR appears to improve dtype consistency for the magnetic PDE simulation (supporting solver_dtype), fix a GeoH5 save edge case, adjust vector-inversion switching logic, and add a Dask-based getJtJdiag implementation for the magnetic PDE simulation.

Changes:

• Cast magnetic PDE RHS / intermediate vectors to solver_dtype before solver application.
• Fix property-group saving when no matching children exist.
• Add Dask getJtJdiag patch for Simulation3DDifferential and import it from simpeg.dask.

All good for me, but check the copilot suggestions and apply as necessary
