feat: IACE CE-Compliance Module — Normen, Risikobewertung, Production Lines

Major features:
- 215 norms library with section references + Beuth URLs (A/B1/B2/C norms)
- 173 hazard patterns with detail fields (scenario, trigger, harm, zone)
- Deterministic pattern matching: Component × Lifecycle × Pattern cross-product
- SIL/PL auto-calculation from S×E×P risk graph
- Risk assessment table with editable S/E/P dropdowns
- Production Line Dashboard with animated station flow (Running Dots)
- IACE process flow + norms coverage on start page
- Non-blocking cookie banner, ProcessFlow SSR fix
- 104 Playwright E2E tests passing
