Fix: milestone routes use milestone_code, config check via backend

- Milestone navigation now uses milestone_code instead of numeric id
- MilestoneDetailPage uses milestone.id (numeric) for project-scoped API calls
- App.tsx checks /config/status on backend first, falls back to wizard
- Added milestone_code to Milestone type
- Fixed MilestoneDetailPage to use fetched milestone.id for sub-queries
