fix(unit-2-auth): Redirect to /setup on API failure; store owner display name

- Router catch block now falls back to { initialized: false } instead of
  silently continuing, preventing unwanted redirect to /login when the
  API call fails at startup
- Add Name field to CreateOwnerRequest and propagate to ApplicationUser.DisplayName
  so the owner's display name is stored during initial setup
