fix(home): 'Play now' resumes the waiting game, not the generic hub (B-002 P2)

Resolve the active session's gameType to its resume route (gameRouteFor) and carry it on
HomeAction.gameRoute / HomeUiState.waitingGameRoute; HomeActionTarget.Game now navigates
there (fallback Play hub). Each game screen auto-joins the couple's active session on open,
so the Home 'Play now' CTA drops the user straight into the actual waiting game.
