fix: revalidate /customize (not /settings) after customize-panel mutations

The invites/onboarding/areas/roles/tiers admin panels moved to /customize, but
their actions still revalidated the old /settings route, so the /customize
Router Cache went stale after a write. Point them at /customize (keeping the
other cross-page revalidations).
