fix(ui): first-login dashboard entrance restored + working Replay Intro

- playDashboardLoadOomph gated itself silent on the one entry that
  should be loud: onboarding is already flagged complete by the time the
  post-wizard dashboard mounts. force flag restores the full oomph there
  while keeping ordinary re-logins quiet (the intentional limit).
- OnboardingDone now hands Login a one-shot finale flag, so the login
  right after the wizard gets the full zoom + oomph even as a regular
  password login — which is exactly the demo flow (and TOTP logins).
- 'Replay intro' on the login screen actually replays: App.vue was
  instantly re-marking the intro as seen on onboarded nodes; an explicit
  one-shot replay flag now overrides every suppression rule (unit
  tested).
