Add two optional fields to the OpenAI STT provider config schema:
- `language`: server-side default language (ISO 639-1) sent to Whisper when
the client doesn't provide one. Useful for non-English deployments where
admins want to predefine the transcription language without requiring each
user to configure it in the browser.
- `extraParams`: arbitrary key-value pairs forwarded to the STT endpoint.
Enables self-hosted Whisper servers (e.g. Speaches, faster-whisper-server)
to receive provider-specific parameters like `vad_filter` (Voice Activity
Detection) which filters silence and prevents hallucinations on empty
audio clips. These params are ignored by the official OpenAI API.
Example librechat.yaml configuration:
```yaml
speech:
stt:
openai:
url: 'http://whisper-server/v1/audio/transcriptions'
apiKey: 'none'
model: 'whisper-large-v3-turbo'
language: 'pl'
extraParams:
vad_filter: true
```
