* docs: FreeCAD wiki updates for three macros
* Fix macro and wiki metadata
* fix: minor bugs in CutObjectForMagnets macro
1. Redundant distToShape call (lines 864-868)
Issue: The _get_inset_point method computed dist_info = cut_face.distToShape(Part.Vertex(inset_point)) at line 841, but then called distToShape again at line 867 with the same arguments.
Fix: Removed the redundant call and reused the already-computed dist_info result.
2. Redundant hide transaction in main() (lines 1907-1914)
Issue: main() had a "Transaction 7: Hide original object" that duplicated the hiding logic already in execute() Transaction 8 (lines 1391-1412). Additionally, the main() version had worse error handling (re-raised exceptions instead of gracefully continuing).
Fix: Removed the redundant transaction block from main(). The execute() method's Transaction 8 already handles hiding the original object properly with graceful error handling.
