refactor(battle-node): drop BattleType.Scripted and the scripted-only builders

Removes the Scripted enum value, the bot's client-shaped emissions (BuildClient*),
the canned opponent turn (BuildOpponent*), and OpponentTurnStartSpin. The shared
server-frame builders (Matched/BattleStart/Deal/Swap/Ready + ComputeHandAfterSwap)
and OpponentJudgeSpin (Bot mode) stay.
