feat(casting): improve track selection and session handling

Browse Source 
implements automatic initialization of audio and subtitle tracks based on server-provided defaults. ensures subtitle selection persists correctly during stream reloads by resolving track indices more reliably.

replaces crypto-based uuid generation with a math-based fallback to ensure compatibility with environments lacking global crypto support. adds missing media source metadata to cast info to improve consistency between the client and receiver.
