fix(town): HouseBuilding CODEC 序列化 residentsUUID，修复存档重载后房屋容量失忆

- 参考 MineBaseBuilding/HuntingBaseBuilding 的 residentsID 写法，CODEC 加
  optionalFieldOf("residentsUUID", List.of()) 默认空集兼容旧档
- 全量构造器加 List<UUID> residentsUUID 参数（residentsUUID 为 final 字段，
  用 addAll 填充）；9 参便捷构造器委托补 List.of()
- 修复症状：重载存档/房屋方块重建后 residentsUUID 恒空 → allocateHouse
  容量判断（以 residentsUUID.size() 为准）把满员房当空房 → 招募可无限超额（实测 6/3）
