Description

Auto-populate the model field in Shelley by fetching available models from the /v1/models API endpoint.

Context

From the discussion thread:

• jra2769: "It would be nice if Shelley auto-filled the 'model' field if the API endpoint reports it supports only one model anyway."
• quangdz_11: "auto load model list from /v1/models is even better"

Proposed Solution

Instead of requiring manual model selection, Shelley should:

1. Query the /v1/models endpoint when connecting to an API
2. Auto-populate the model field based on available models from the endpoint
3. If only one model is available, auto-select it
4. If multiple models are available, provide a list for selection

This would improve the user experience by reducing manual configuration steps.
