Fix duplicate API calls and use real backend data in threads tab

- Remove duplicate getNodeThreads query that was calling the same API endpoint
- Update Threads component to use existing getNodeInfo query data
- Add Threads field to TSystemStateInfo interface to properly type the thread data
- Threads tab now displays real backend data without duplicate API calls
- Fixes both issues: no more duplicate sysinfo calls and threads data is properly displayed
