feat(web): merge Song Importer into Global Suche (one unified field)

The importer no longer has its own sidebar/bottom-nav entry. The Global
Suche field now handles both jobs: plain text runs the Deezer search;
a pasted Spotify/SoundCloud/YouTube link switches into importer mode
(badge + "Importieren" button + preview), matching the Android app and
tidying the left nav.

- New onGlobalInput/tryImporterResolve; importer DOM moved into
  page-discover; old page-spotify-importer removed; routing cleaned up.
- Existing resolvers unchanged (still read the mirrored importer-link-input).
