server: improve llm warmup exception handling

If LLM is stuck to warm or an exception happen in the pipeline, then the processor responsible for the exception fail, and there is no fallback. So audio continue to arrive, but no processing happen.While this should be done right especially after disconnection, still, we should ignore llm warmup issue and just go.

Closes #140
