fix(e2e): 3 CI failures — org-multi-tenant timeout, dual-view events, supervisor path

- org-multi-tenant.spec.ts: goto timeout 60s→120s (same fix as previous)
- clazz-dual-view.spec.ts: use toPass to wait for .fc-event re-render after view switch
- supervisor-features.spec.ts: navigate to /teacher/home after role selection
