Add Node.js to Docker image; use web player client only

Browse Source 
Node.js is required by yt-dlp to solve YouTube's n-challenge (format URL
deobfuscation). Without it the web client returns no video formats.

The tv and ios player clients were removed — both require GVS PO tokens
that we don't have, so they only produce warnings and block every request.
The web client with Node.js installed gives 30+ formats and works cleanly.
