Eliminated redundant serverinfo RCON polling from the serverInfo page.
It now subscribes to the header's serverinfo-update CustomEvent instead.
Key changes:
- app.js: cache last serverinfo in window._lastServerInfo and dispatch
serverinfo-update event so pages can pick up data immediately
- serverInfo.js: replaced setInterval-based polling with event listener
plus immediate _lastServerInfo cache check, eliminating the initial
blank page state and duplicate RCON requests
