Migrate remove_deep to remove_deep2 across API modules

remove_deep is deprecated and can silently delete elements still in use.
remove_deep2 requires zero inverses before removal, making it safer.
Also fixes a double-removal bug in remove_grid_axis and prevents
removing the last prop template from a pset template.
