Add support for Openrouter

Openrouter uses an OpenAI compatible API so all you need to do is set the OPENAI_ENDPOINT and OPENAI_API_KEY to those of Openrouter.

OPENAI_ENDPOINT=https://openrouter.ai/api/v1
OPENAI_API_KEY=<your openrouter api key>

In the UI set the LLM provider to openai and to get the proper model name format:

OpenRouter > Models
Select model to get details.
select API tab
Look at the code block example and select the model name there.

Can confirm it works, I tried out the demo :)

1. Set endpoint and api key like described by @rmensing

2. Set model (I used deepseek v3) (deepseek/deepseek-chat)
   

Then I checked OpenRouter usage:

How can you select deepseek/deepseek-chat after setting openai as provider? That should not be possible!

If you set the openrouter details, like explained in the previous post, then I guess it would be possible. Not if you use openAI settings

The above workaround settings are forgotten and need to be set each time the page is refreshed. Just FYI please.
