refactor(battle-node): rename ScriptedLifecycle->ServerBattleFrames, ScriptedProfiles->BattleFrameDefaults

Pure rename. These hold the shared server-authored frame builders used by every
battle mode's handshake/mulligan dispatch — the 'Scripted' name was a historical
accident that hid the PvP/Bot crossover. No behavior change.
