fix: search all Wolf Steam homes for AppID prefix, not just head -1

With multiple WolfSteam containers running, _steam_home() picks the first
Steam directory found which may not contain the target game's prefix.
_apply_ea_fix now scans all Wolf Steam homes and selects the one that has
the AppID's Proton prefix, falling back to the original behavior if none
match.
