v4.2.1: plain-language game copy and a balance fetch on login

The lobby and every game screen now speak to a player, not an operator: each game has one how-to sentence, and the table headers, limits, RTP, paytable and server-timing notes are gone. The account and balance are fetched whenever a session signs in, including stored-credential auto-login, so the header is filled before the lobby appears.
