fix(audio): align AudioContext to 48kHz up front for Opus streams

Opus resolved its 48kHz context lazily on the first chunk, close()ing and rebuilding the live graph mid-decode. Move the recreate into initializeStreaming so it runs before any bytes flow; the lazy call early-returns. WAV path unchanged.
