Fix SSR and defensive coding for Keycloak integration

- Add proper SSR guards and error handling
- Make authentication middleware more defensive
- Add null checks in useUnifiedAuth composable
- Prevent JavaScript errors from breaking page load
- Prioritize Directus auth over Keycloak for stability
