fix(speech): bound TTS/STT voice-list and transcription JSON response reads
Route success JSON reads through readProviderJsonResponse (16 MiB cap) in azure-speech, elevenlabs, microsoft, minimax/tts, xai/stt, and openrouter/media-understanding to prevent OOM from oversized or hostile endpoint responses. Mirrors the response-limit campaign already applied to other provider paths. AI-assisted. Co-authored-by: Cursor <[email protected]>
