Battle Sandbox v2: up to 8 enemies, location/route picker, and spread/camera planner

• The Battle Sandbox tab in LiveBattleLab is no longer a vertical A/B/C stack: it now has a compact 8-enemy slot layout with per-slot HP and quick AI. Routes can be selected from the decoded btl.bin list (map/battleId/field/group/formation) or edited manually; Prepare route writes the resolved btl_* formation slots and MonsterLive positions with .sandbox.btl.bak, reusing BattleArenaAuthor, Battle_File.WriteWithFormationSlots(), and BattleArenaPositionWriter. The planner offers spreads (2 compact rows, wide, boss+adds, corridor, ring) and computes a camera framing recommendation for all active monsters; automatic camera writing remains honestly deferred to Aurora/RT2. Force Battle still requires the connected DINPUT8 probe. Solution build: 0 errors / 361 warnings; local screenshot at work/screenshots/battle-sandbox-tab.png
