perf(admin): full-stack performance optimization for all list tables

- Implemented server-side search, infinite scrolling, and list virtualization for Tenants, Users, and Audit Logs.
- Backend: Enhanced Repository, Service, and Handler layers to support 'search' and 'cursor' parameters.
- Frontend: Integrated @tanstack/react-virtual and useInfiniteQuery for high-performance rendering.
- Quality: Updated all unit tests and E2E tests to match the new asynchronous server-side search architecture.
- i18n: Synced all translation keys and cleaned up unused resources.
