fix: Service 层移除直接持有的 *gorm.DB,引入 Repository Transaction 方法
- ReactionStore/FollowStore/EnergyStore/FavoriteStore 接口新增 Transaction 方法 - EnergyStore.Transaction 支持跨仓库事务(EnergyStore + FundStore) - ReactionRepo/FollowRepo/FavoriteRepo/EnergyRepo 实现 Transaction 方法 - ReactionRepo 新增 GetPostLikesCount 方法,消除 Service 直查 DB - ReactionService/FollowService/FavoriteService/EnergyService 移除 db 字段 - EnergyRepo 通过 SetFundStore 注入 FundStore 用于跨仓库事务 - 更新 deps_extra.go 构造函数调用
