[ENHANCEMENT] Get the Friendli model list from the Friendli API #2332

Problem (one or two sentences)

Zoo Code shows a fixed list of Friendli models. This list goes out of date when Friendli adds or removes models.

Context (who is affected and when)

This affects Friendli users. New models do not show in the model picker. Removed models still show and fail when a user selects them.

Desired behavior (conceptual, not technical)

The Friendli model picker shows the models that Friendli serves now. Each model shows its correct context window, max output, pricing, and reasoning effort values.

Constraints / preferences (optional)

Get the model list from the public Friendli endpoint https://api.friendli.ai/serverless/v1/models. This endpoint does not need an API key. Keep the current fixed list as a fallback if the request fails.
