feat(squad): in-memory squad/lobby state + wire squad functions

Adds SquadService (singleton, process-local) tracking squads by the squadId the client shares across party members, plus a user->squad index so TryGetCompleteSquadInfo (no squadId in request) can resolve the caller's squad. Members are lazily registered on any squad call. - TryGetCompleteSquadInfo: returns the caller's real squad. - SquadMemberReadyForMatch: joins the squad, records readiness/map, returns the squad + whether everyone is ready. - SquadMemberSelectedMap: records the member's selected map. - DbUserService.FindByIdAsync: resolve display name for squad members. Groundwork for the station lobby; assumes the client drives squads via these calls with a shared squadId (to confirm with a 2-client session). Real-time SignalR push (unknown event names) deferred; the squad is carried in responses + TryGetCompleteSquadInfo for now. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

+// In-memory squad/lobby state. Squads are keyed by the squadId the client provides on the
+// SquadMember* calls (the client forms the party and shares a squadId; each member's client
+// then calls the backend with it). A member is (lazily) registered into that squad on any
+// squad call, and the current squad for a user is tracked so TryGetCompleteSquadInfo — which
+// carries no squadId — can still return it. State is process-local (fine for a small server).
