fix(onboarding): hard-navigate to /dashboard after finish

router.replace + router.refresh occasionally raced against the app
layout's hasCompletedOnboarding check — the audit_log row insert
hadn't been observed by the new request yet, so the layout bounced
the user straight back to /onboarding with no visible feedback.

Use window.location.href for a hard reload after the action resolves.
Slower (~50ms) but deterministic. Also surfaces thrown errors in the
toast instead of silently returning.

Side-effects:
- Drop unused useRouter import
