feat(cra): Cyber-trifft-CE mit echten IACE-Safety-Functions

useCRA leitet aus den Hazards+Mitigations DES IACE-Projekts cyber-relevante
safety_functions ab (Bewegung/Quetschen/safety_function_failure/Pneumatik →
prevent_unexpected_actuation; Signal/Sensor/Kommunikation → signal_integrity;
rein physische wie Thermik/Ergonomie ausgeschlossen) und gibt sie statt der
Demo-Hardcodes an /assess. build_cross_links zeigt dann, welche REALE
Projekt-Schutzmassnahme ein Cyber-Befund wieder oeffnet. Fallback auf Demo-Set,
bis die Projekt-Hazards geladen sind.
