Merge branch 'main' into docs/azure-instance-name-clarification

- Add Azure OpenAI STT/TTS examples to librechat.example.yaml
- Clarify that instanceName should be the <NAME> part only (e.g., 'my-instance')
- Not the full URL (e.g., 'my-instance.cognitiveservices.azure.com')
- Add note that full domain format is still supported for backward compatibility

Examples:
- Correct: instanceName: 'my-instance'
- Also works: instanceName: 'my-instance.cognitiveservices.azure.com'
