Jury inline doc preview, download fix, category tags, admin eval reset

- Replace MultiWindowDocViewer with FileViewer for inline previews (PDF/image/video/Office)
- Fix cross-origin download using fetch+blob instead of <a download>
- Show Startup/Business Concept badge on jury project detail + evaluate pages
- Add admin resetEvaluation procedure with audit logging
- Add dropdown menu on admin assignment rows with Reset Evaluation + Delete
- Make file action buttons responsive on mobile (separate row below file info)
