feat(replay): add ViewerBattleHistory entity + migration

New table backs /replay/info; composite PK (ViewerId, BattleId), index on (ViewerId, CreateTime) for the newest-first list query. 50-row per-viewer retention enforced by BattleHistoryWriter (next commit). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
