The composer preview tab was missing webxdc embeds because it manually rendered only videos and audio, while webxdc rendering lived exclusively inside NoteCard. Extract NoteMedia into a shared component and ImetaEntry/parseImetaMap into a shared utility, then wire them into the ComposeBox preview with proper imeta tag generation on the mock event.
