fix(copilot): stream timeout, long-running tool polling, and CreateAgent UI refresh (#12070)

Agent generation completes on the backend but the UI does not
update/refresh to show the result.

### Changes 🏗️

![Uploading Screenshot 2026-02-13 at 00.44.54.png…]()


- **Stream start timeout (12s):** If the backend doesn't begin streaming
within 12 seconds of submitting a message, the stream is aborted and a
destructive toast is shown to the user.
- **Long-running tool polling:** Added `useLongRunningToolPolling` hook
that polls the session endpoint every 1.5s while a tool output is in an
operating state (`operation_started` / `operation_pending` /
`operation_in_progress`). When the backend completes, messages are
refreshed so the UI reflects the final result.
- **CreateAgent UI improvements:** Replaced the orbit loader / progress
bar with a mini-game, added expanded accordion for saved agents, and
improved the saved-agent card with image, icons, and links that open in
new tabs.
- **Backend tweaks:** Added `image_url` to `CreateAgentToolOutput`,
minor model/service updates for the dummy agent generator.

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
- [x] Send a message and verify the stream starts within 12s or a toast
appears
- [x] Trigger agent creation and verify the UI updates when the backend
completes
- [x] Verify the saved-agent card renders correctly with image, links,
and icons
