Consolidated round management, AI filtering enhancements, MinIO storage restructure

- Fix STAGE_ACTIVE bug in assignment router (now ROUND_ACTIVE)
- Add evaluation form CRUD (getForm + upsertForm endpoints)
- Add advanceProjects mutation for manual project advancement
- Rewrite round detail page: 7-tab consolidated interface
- Add filtering rules UI with full CRUD (field-based, document check, AI screening)
- Add pageCount field to ProjectFile for document page limit filtering
- Enhance AI filtering: per-file page limits, category/region-aware guidelines
- Restructure MinIO paths: {ProjectName}/{RoundName}/{timestamp}-{file}
- Update dashboard and pool page links from /admin/competitions to /admin/rounds
