Fix multi-user authentication and WebSocket issues

- Fix CLI WebSocket port (9101 vs 9103) in both status and authenticateUser
- Add researcher_user and analyst_user to server config with proper permissions
- Fix API key hashes for all users (complete 64-char SHA256)
- Enable IP whitelist with localhost and private network ranges
- Fix memory leaks in WebSocket handshake (proper key cleanup)
- Fix binary character display in server responses
- All authentication tests now pass: admin, researcher, analyst

Status: Multi-user authentication fully functional
