Follow-up to #14785. Routes the tests that still hand-rolled temp paths through the shared helpers and unifies the temp guards. - Add ScopedTemporaryDir and a shared ScopedTemporaryPath base under it and ScopedTemporaryFile. - Move test_3mf's round-trip .3mf output out of the TEST_DATA_DIR source tree (a fixed-name leak) and test_toolordering's fixed-name temp .gcode (a sharding collision) onto ScopedTemporaryFile. - Move test_config, test_slicing_pipeline_bindings, the test_3mf backup dirs, and test_preset_bundle_loading onto the guards. - Make slic3rutils ScopedDataDir compose ScopedTemporaryDir; dedupe test_network_versions' fixture and delete test_plugin_lifecycle's duplicate.
