Provide the smoothest / white glove experience that guide users through their initial setup.

Key User Stories

This screen will appear when:

This screen aims to guide users how to start

• User can download an on-device model to use or
• User can set up a cloud model

Sorry for the confusion, here's my update.

This screen will appear when:

User doesn't have any model + doesn't any thread

---

This is the only case, when there's no model but users still have old threads, it should be a separate case, i'm working on it, will let you guys know when it's finalized.

@imtuyethan is this issue fixed yet? If not, can you update to reflect what remains to be done.
