feat: users can tell which are remote models (like openai api) in the UI

[freelerobot]

Problem We need a few UI states, now that we're incorporating remote models (like openai gpts):

• local model vs remote model
• when users are offline, what do we show them
• how are model parameters different?
• where do users input api key?

@imtuyethan FYI for future reference, when a design is approved, please help to:

1. Remove: needs designs label
2. Add: needs specs label
3. Assign to me

Thanks!
