Implement Prototype 1 improvements: unified members, project filters, audit expansion, filtering rounds, special awards

- Unified Member Management: merge /admin/users and /admin/mentors into /admin/members with role tabs, search, pagination
- Project List Filters: add search, multi-status filter, round/category/country selects, boolean toggles, URL persistence
- Audit Log Expansion: track logins, round state changes, evaluation submissions, file access, role changes via shared logAudit utility
- Founding Date Field: add foundedAt to Project model with CSV import support
- Filtering Round System: configurable rules (field-based, document check, AI screening), execution engine, results review with override/reinstate
- Special Awards System: named awards with eligibility criteria, dedicated jury, PICK_WINNER/RANKED/SCORED voting modes, AI eligibility
- Dashboard resilience: wrap heavy queries in try-catch to prevent error boundary on transient DB failures
- Reusable pagination component extracted to src/components/shared/pagination.tsx
- Old /admin/users and /admin/mentors routes redirect to /admin/members
- Prisma migration for all schema additions (additive, no data loss)
