Orca 1.8.2

Fixed

• Setup-wizard OAuth no longer looks stuck. The AI-provider OAuth step ran a spinner while showing the authorization URL and the paste-code prompt, hiding them — the sign-in appeared frozen and never surfaced the field to paste the redirect URL back. It now uses the same linear paste-back flow as the web dialog: show the URL (open the browser best-effort), then prompt for the pasted redirect URL / code with nothing competing for the screen.
