feat: add telemetry error capture to Mistral provider

- Import TelemetryService and ApiProviderError
- Add providerName property to MistralHandler class
- Wrap createMessage() client.chat.stream() call in try/catch with telemetry capture
- Add telemetry capture in completePrompt() catch block
- Add tests to verify telemetry is called on error for both methods

Follows the pattern established in PR #10073 for OpenRouter provider.
