Show and label WebDAV/SMB video streams in the quality selector

Media-source streams from WebDAV/SMB were invisible in the Video list:
the filter required remote URLs to carry a resolution, which
MediaFile.toStream never sets. Include non-adaptive remote streams
without resolution (only media sources produce those), extend the
mpv-track display enrichment to the currently playing stream regardless
of URL scheme, and classify metadata-less streams as recommended — a
nil codec previously counted as software-decoded, hiding the row behind
advanced mode with a spurious warning. The warning now uses the
enriched codec.
