Extract the push-undo → per-handle → invalidate → dirty → refresh contract into one helper on OpenCADStudio. The helper is the single source of truth for property-op side effects, so future property handlers can't forget the cache invalidation or the panel refresh. Note: MATCHPROP now no-ops when the destination selection is empty (previously it marked the tab dirty and refreshed the panel). This is a minor correctness improvement; restore the old behaviour with a 2-line guard at the MATCHPROP call site if desired. test app::properties::apply_property_op_tests::empty_handles_does_not_invoke_or_dirty test app::properties::apply_property_op_tests::applies_to_each_handle_sets_dirty_and_mutates test app::properties::apply_property_op_tests::missing_entity_does_not_abort_loop
