Enable AudioContext and proxy for all users, not just extension users

Browse source 
- Set crossorigin="anonymous" as a static HTML attribute on audio/video elements
  so all users can use createMediaElementSource (required for Web Audio API)
- Remove window.__tidalOriginExtension guards from AudioContext init/changeSource:
  binaural DSP, EQ, M/S processing, and audio graph now active for everyone
- Route direct (non-DASH) stream URLs through getProxyUrl in player.js so
  non-extension users get CORS headers from the proxy for lossless/MP4 audio
- Proxy preloader src as well so browser cache warms with the proxied URL
- Add idempotency guard in getProxyUrl to prevent double-proxying when Shaka
  retries segment requests (proxied URL still contains "tidal.com" in params)
- Extension users: still bypass proxy and get CDN URLs directly (unchanged)
