OpenRouter integration is broken

[EvilBox]

What happened?

OpenRouter integration is broken in docker-compose env.

Expected behavior:
Openrouter is available for selection after adding the key to .env. Without headaches, unicorns, or disco dancing :)

Version Information

all containers with latest tag

Steps to Reproduce

1. git clone https://github.com/danny-avila/LibreChat.git
2. mv .env.example to .env
3. Create key https://openrouter.ai/settings/keys
4. Uncomment OPENROUTER_KEY and add key from prev step
5. docker-compose up -d
6. Go to webui and you will not see openrouter in the interface

What browsers are you seeing the problem on?

Chrome

You need to configure it as a custom endpoint:

Thanks! But why do we need .env then? Why do we need all this automation and tons of variables? Why do we need OPENROUTER_KEY env?
If, in the end, we go and write the config manually. I really don't understand ...
