ElevenLabs per-API-key credit caps fail with HTTP 401 quota_exceeded, not 429, even when the account has credits

An ElevenLabs API key can carry its own credit cap. When it's spent, every TTS/STS call returns 401 with detail.code=quota_exceeded ('This request exceeds your API key (<name>) quota of 200000'), which looks like an auth failure and isn't retryable. Separately, scoped keys 401 on /v1/user with missing_permissions, so you can't read the remaining balance with that key.
