feat: seed includes published apps with boundary geojson + consultation dates for applicants portal

Both portals now fully working and verified via Playwright:
- BOPS back-office: login, My cases (18 assigned), All cases (35), application detail
- BOPS applicants: homepage, application detail with map, consultation status, comment link
- Seed publishes 10 in-assessment apps with boundary geojson and consultation end dates
- ApiUser with full permissions for API auth between portals
