/portal/onboarding is only a step in the Google sign-in flow. Redirect to
login unless the login page's onboard_email handoff hint is present (and the
session is authenticated), instead of showing an empty form on direct/typed
URL access. Hold rendering until the check passes to avoid a form flash, and
clear the hint once onboarding completes so it can't be reused.
After a Google sign-in with no CRM profile, route to /portal/onboarding — the
registration flow in mode='onboard': email skipped (Google-verified, prefilled
via getUserEmail), sets a password (updateUser) so email+password login also
works, skips the OTP-verify step, and persists the profile via crm.account.register.
Existing-profile users go straight to the dashboard. Bumps SDK ^0.2.3.
