fix: circular import causing navigate undefined; unified importer input

- Remove top-level ui.js import from soundcloud.js (broke views.js→soundcloud.js→ui.js→views.js cycle)
- Use window.executeSpotifyDownload() instead to avoid the circular dep
- Merge Spotify + SoundCloud into one unified URL input that auto-detects
  the service and colors the badge/button accordingly
- resolveImporterLink() routes to the correct handler based on URL
