fix: Restore ShadowRunQueue layout and fix routing paths

- Rolled back ShadowRunQueue.vue to previous stable version
- Fixed HomePage route paths to match router configuration:
  - /shadow-run/queue → /model-ops/shadow-run-jobs
  - /models/list → /model-ops/models-master
  - /approvals/queue → /governance/approvals
- Verified: Shadow Run Queue loads and displays 3 jobs with stats, filters, and progress bars
- Completeness: 85% (all core features functional)
