Previously, get_backend() would return 'ipyleaflet' whenever folium import failed, without checking if the object was an ipyleaflet.Map. This could cause crashes in Layer.add_to() methods when wrong backend was selected. This fix: - Properly checks object types for both folium and ipyleaflet - Raises clear ValueError when neither backend matches - Adds comprehensive tests covering all edge cases - Follows GRASS coding standards Bug discovered while writing tests - original logic made dangerous assumptions that could break map functionality. AI assistance used for codebase understanding and test design. All code changes and testing were performed by the contributor.

This issue was discovered while writing tests for
grass.jupyteras part of the GSoC test-of-skills tasks. I have also opened issue #7239 for tracking this bug.
