Change default filename_prefix on all previewable save nodes (image, video,
audio, 3D, SVG) from 'ComfyUI' to 'ComfyUI_%year%%month%%day%-%hour%%minute%%second%'.

This leverages the existing compute_vars template system in
get_save_image_path — zero new backend code needed. Each output gets a
unique filename per second, preventing browser cache from showing stale
previews when files are overwritten.

Users can customize or remove the template from the node widget.
Existing workflows retain their saved prefix value (only new nodes
get the new default). Custom nodes are unaffected — they define their
own defaults independently.
