Refactor track recommendation logic and add TrackRecType enum

Moved recommendation query generation from Node to Track using the new TrackRecType enum, simplifying and centralizing platform-specific recommendation formatting. Updated related methods to use Track.get_recommendations, removed Node.get_recommendations, and improved enum handling for search platform matching. Also exposed TrackRecType in voicelink.__init__.
