Audio URLs with `audio/*` MIME types in NIP-92 imeta tags were silently dropped (createMediaContent returned null) because only `image/` and `video/` prefixes were checked. They now map to MediaUrlVideo, which Media3/ExoPlayer already handles correctly for audio playback. Also adds common audio extensions (ogg, wav, flac, aac, opus, m4a) to the extension-based fallback so audio files without imeta tags are also detected.
