Performance optimization, applicant portal, and missing DB migration

Performance:
- Convert admin dashboard from SSR to client-side tRPC (fixes 503/ChunkLoadError)
- New dashboard.getStats tRPC endpoint batches 16 queries into single response
- Parallelize jury dashboard queries (assignments + gracePeriods via Promise.all)
- Add project.getFullDetail combined endpoint (project + assignments + stats)
- Configure Prisma connection pool (connection_limit=20, pool_timeout=10)
- Add optimizePackageImports for lucide-react tree-shaking
- Increase React Query staleTime from 1min to 5min

Applicant portal:
- Add applicant layout, nav, dashboard, documents, team, and mentor pages
- Add applicant router with document and team management endpoints
- Add chunk error recovery utility
- Update role nav and auth redirect for applicant role

Database:
- Add migration for missing schema elements (SpecialAward job tracking
  columns, WizardTemplate table, missing indexes)
