feat: make hook redirect IP configurable from launcher

Browse Source 
The DLL now reads openfut.cfg from its own directory on DLL_PROCESS_ATTACH
and uses the IP it contains as the redirect target instead of hardcoding
127.0.0.1. Falls back to 127.0.0.1 if the file is absent.

The launcher writes openfut.cfg alongside version.dll when deploying, and
the Setup tab exposes a "Redirect IP" field with an "Update" button that
rewrites openfut.cfg in-place without redeploying the DLL. Useful when
running the emulator on a different machine on the LAN.
