Add search, filters, pagination to admin users table

- Add emailVerified filter (true/false/any) to UsersSearch component
- Wire emailVerified param through page searchParams, where clause, and pageUrl helper
- Preserve emailVerified in pagination links alongside existing search/role/balance params
- Update pagination label to "Страница X из Y · Всего: N"
