Problem (one or two sentences)

When I'm using OpenRouter as Embedder provider I can't specify a Custom Url like in the OpenRouter configuration.

Context (who is affected and when)

This affects users who need to point Roo Code to a self-hosted, proxy, or third-party OpenRouter-compatible endpoint for privacy or cost management

Desired behavior (conceptual, not technical)

Include a Custom URL checkbox and input for handling a Custom URL of OpenRouter, like in OpenRouter provider configuration.
