feat(iace-fmea): KI-Vorschlag Uebernehmen/Ablehnen flow + AP unit tests

Closes the loose end from IACE Phase 5 handover: the LLM FM-suggest button
existed and the backend endpoint was wired, but accepted suggestions had
no path into the FMEA worksheet.

Hook (useFMEA.ts):
- acceptSuggestion(fm, componentId): builds an FMEARow from FM defaults,
  prepends to rows (sorted by RPZ), removes the FM from suggestions.
  No-ops + drops the suggestion when (component, fm.id) is already in rows.
- rejectSuggestion(fmId): drops the FM from suggestions list.

Page (fmea/page.tsx):
- Suggestion cards now have explicit Uebernehmen / Ablehnen buttons.
- Counter "X Vorschlaege uebernommen" tracks accept count for the run.
- RPZ in each suggestion is colour-coded (red >200, orange >100).
- Hinweis line explains S/O/D adjustability after acceptance.
- acceptedCount auto-resets when suggesting starts or panel closes.

Tests (useFMEA.test.ts):
- 8 calculateAP cases covering AIAG-VDA 2019 boundary points for severity
  10 / 9 / 7 / 5 / 3, validating the H/M/L action priority matrix.

LOC: fmea/page.tsx hits 320 (soft target 300, well under 500 hard cap).
