GEOPY-3102 - Unwanted augmentation of active cells for airborne receivers and large loop source

[Copilot]

🟡 Changes recommended

A targeted regression test is needed because existing assertions do not distinguish the corrected cell selection from the previous behaviour.

What changed in this PR

This PR addresses GEOPY-3102 by preventing large-loop receivers from unnecessarily expanding the inversion’s active cells.

Changes:

• Restricts large-loop TreeMesh cell selection to transmitter paths.
• Updates ground TEM inversion reference targets.

File	Description
tests/​run_tests/​driver_ground_tem_test.py	Adjusts expected inversion metrics.
simpeg_drivers/​utils/​utils.py	Excludes receiver locations from large-loop cell selection.
