GEOPY-2862 - Inversion crash on tile mesh creation transferring data

[Copilot]

Pull request overview

This PR updates octree mesh cell-convention handling to correctly permute attached child data when cell ordering is adjusted, and adds a test assertion related to that workflow.

Changes:

• Fix ensure_cell_convention so it reorders np.ndarray-backed child values instead of skipping them.
• Add an assertion in test_mesh_visual_parameters_copy calling ensure_cell_convention.
