Merge S4-10: mark scheme editor + SpecPoint picker

- Add /exam-marker/:templateId/marks route with MarkSchemePage
- Per-Part mark scheme editor: points/levels/parts/checklist/free forms
- SpecPoint picker via GET /api/exam/specs/{spec_code}/points (falls back to manual spec_ref when endpoint 404s)
- Manual neo4j-sync button; ASSESSES edge verified in cc.public.exams
- Edit marks button on each template card in dashboard
- Merge-resolved: AppRoutes, index.ts, exam.types.ts, ExamDashboardPage (kept grouped UI + added Edit marks button)
