fix(e2e): goTo wartet auf h1 statt nav fuer zuverlaessigere Hydration

Root cause der 16 overview-Failures: goTo kehrte zu frueh zurueck weil
nav sofort sichtbar ist (SSR), aber der Main-Content (Projektstatus etc.)
erst nach API-Fetch rendert. Jetzt wartet goTo auf h1 (das erst nach
dem project-Fetch erscheint) + 1s Buffer.
