UniverSR Load Video Audio (Path) mirrors FoleyTuneVideoLoader: takes an
absolute video_path (for files outside input/) and outputs the same
(UNIVERSR_VIDEO, AUDIO). Shared load body factored into _load_video_audio;
registered for the inline preview (post-run) in the web extension.

Replace the path+dropdown loader (and its non-rendering ui.gifs) with one
node mirroring FoleyTuneVideoLoaderUpload: a `video` upload widget with
drag-drop and an inline video preview, shipped via web/js/UniverSRVideo.js
(adapted from FoleyTuneVideo.js) + WEB_DIRECTORY.
The loader now outputs (UNIVERSR_VIDEO, AUDIO) so you can super-resolve the
audio and remux it. Updated the example workflow output order and README.
