[Bug]: Librechat doesn't wait until Ollama has loaded model

[vlbosch]

What happened?

When starting a conversation with a model served via Ollama, it sometimes happens the prompt stops prematurely with an ETIMEDOUT error. After resending the prompt, it is answered correctly, but only because the model has been loaded by then. With larger models (like Command R Plus), it takes several retries.

Steps to Reproduce

1. Start a chat with an Ollama-served model
2. Prompt the model
3. Send the prompt
4. See the general error message appear

I tested a bit more. Even when the model is loaded, but prompted with a large prompt, a timeout occurs. I think that the timeout should be removed when using Ollama, and only present an error when Ollama does.

@danny-avila Did you have a chance to look into this issue? Would be great if timeouts for custom endpoints can be changed and/or disabled completely. Thanks!
