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
