feat(ai-sdk): keep cyber/AI hazards out of the traditional CE hazard log

InitializeProject created hazards for every matched pattern, so native
cybersecurity/AI topics (unauthorized access, firmware manipulation, missing
SBOM, ...) mixed into the ISO 12100 hazard log. Route the security categories
(frontend groups I. Cyber/Netzwerk + J. KI) to the CRA module instead —
generically for EVERY project, enforced centrally in InitializeProject.

The split is by the nature of the hazard, not the component: functional-safety
control faults stay in CE (software faults, lost safety functions, config
errors, bus failures, botched updates) — they are random/systematic faults,
not attacks, and feed the CRA safety-function bridge. This holds whether the
controller is a bought-in CE-marked PLC or the manufacturer's own control.

+// the cybersecurity assessment (Cyber Resilience Act) are two distinct steps.
+// IACE owns the traditional, physical + functional-safety hazards; the CRA
+// module (/sdk/iace/{id}/cra) owns the native cyber/AI topics and re-examines
+// which safety functions a cyber attack can re-open (see iace-safety-bridge).
+//
+// The split is by the NATURE of the hazard, not by the component: a control
+// fault, bus failure or botched update is FUNCTIONAL safety (random/systematic
+// fault) and stays in CE — independent of whether the controller is a bought-in
+// CE-marked PLC or the manufacturer's own embedded control. Only the security
+// PROPERTIES against malicious actors (access control, firmware/update
+// integrity, SBOM, vulnerability handling, default passwords) are CRA.
+//
+// Functional-safety control categories (software_control, software_fault,
+// safety_function_failure, configuration_error, communication_failure,
+// update_failure, sensor_fault, …) therefore intentionally STAY in IACE — they
