TPG.State.ResetRound

Reset per-round state and mark the round live. Refills both ticket pools to TPG.Config.startingTickets, zeroes both teams' spent limits, stamps the start time, clears every player's duplicator cooldown, paste grace and per-round stats, and resets economy wallets if that mode is running this round. Called from tpg.rounds.Setup, after the map cleanup and before objectives spawn.
