refactor: update remnawave API types for v2.7.0

- ServerInfo: remove cpu_physical_cores, memory_available
- NodeInfo: replace cpu_count/cpu_model/total_ram with versions/system,
  xray_uptime changed to number, users_online now required
- NodeStatus: same field updates, remove dead uptime field
- Extract formatUptime to shared utils/format.ts
- Update AdminRemnawave and AdminDashboard components
