chore(plugins,ci): remove livekit audio switch patch plugin and simplify build config

Remove the LiveKit audio switch patch plugin as it's no longer needed after the JitPack
repository was restricted to GitHub packages only. Simplify CI by removing npm caching and
Android NDK caching/installation steps. Update privacy policy and terms of service to
reflect JPush SDK naming changes.
