fix(scripts): update server paths for new VPS location

Start script now defaults to /home/fractured-panel/azeroth-server and
passes -c flags so binaries find configs regardless of compiled-in path.
Update script gains --prefix flag to override CMAKE_INSTALL_PREFIX
(persisted to conf/config.sh) during rebuild.
