Feature request: Check for new models manually or periodically

[jhoermann]

Problem When downloading new models through the CLI they won't appear in the models list. Restart is required to get a new list of models.

Solution Options

1. Ability to manually check for new models with a 'Update models list' button
2. Periodically check for new models by calling the ollama server models list endpoint every X minute(s)

What would you prefer @fmaclen?

We update the models list when you refresh the page or when clicking on the Sessions link in the sidebar. I'm leaning towards adding a "Refresh" button next to the models list.
