 - [x] M5: configuration — coupler settings forms (watchdog time/masks/type/close-on-timeout via 0x1000–0x100B, response delay 0x1037, idle timeout 0x1030) with the device's own validation surfaced (writes refused while the watchdog runs → field error); module list editor over the 13-article catalog with SAVE CONFIG → live process-image rebuild (`rebuild_node`: datastore survives, values clear like a KBUS reset, 0x1022–0x1025 and 0x2030+ updated) + persistence to the node-config YAML via a comment-preserving custom emitter.
