- New zigbee props (approve + first-time re-import) ship with visible=false so the canvas card stays clean. User opts in from the right panel. - On re-import of an already-approved node, merge instead of overwrite: keys already present keep their visible flag (and any user-edited value is replaced with the freshly imported one), brand-new keys are appended hidden. Non-zigbee custom properties are preserved untouched.
