Subject: [PATCH] game-server: catch-all request capture for squad-invite RE

Log every unrouted POST at Warning [CAPTURE UNROUTED] (reveals native PlayFab
endpoints the emulator doesn't implement, e.g. /Group/CreateGroup, /Lobby/*) and
every social/squad/invite/friend/matchmaking call (path or body) at Information
[CAPTURE SOCIAL]. Lets us pin the exact invite mechanism when reproduced in game.
