Add LAN discovery and Local servers UI

Browse Source 
Adds LAN server discovery and a Local tab in the multiplayer UI so clients can find relays on the same LAN. Introduces a new F4T::LanDiscovery module (plugin/include/F4TLanDiscovery.h, plugin/src/F4TLanDiscovery.cpp) that probes LAN hosts via UDP discover (port 7778) and TCP welcome fallback (port 7777). Server-side support includes a UDP responder (server/lan_discovery.py) and integration in server_core.py to start/stop discovery.

Plugin changes (F4TServerBrowserBridge/Data) add background scanning, dispatch results to the game thread, new local-server storage and events (scanLocalServers, localServersUpdated, localScanStarted/localScanFinished), and small join/recent handling updates. UI changes (ui/.../app.js and components) add localServers state, scanning UX, Recent persistence (localStorage), and join logic for local/direct entries. Docs updated (docs/protocol.md, docs/dev-log.md, server/README.md) and build script links iphlpapi. Also removes two unused exported sprite PNGs.
