feat: 代理商资金可见性重构（agent-fund-visibility）

- 将 GET /shops/commission-summary 重命名为 GET /shops/fund-summary，
  响应新增 main_balance、main_frozen_balance 两个预充值钱包字段
- 新增 GET /shops/:id/main-wallet/transactions 预充值钱包流水接口
- 将佣金统计、每日统计、发起提现从 /my/ 路径迁移至 /shops/:id/ 路径：
  GET /shops/:id/commission-stats
  GET /shops/:id/commission-daily-stats
  POST /shops/:id/withdrawal-requests
- 删除 MyCommissionService、MyCommissionHandler 及全部 /my/ 路由
- 补齐 ListShopWithdrawalRequests、ListShopCommissionRecords 的
  CanManageShop 越权校验（安全修复）
- 提现接口增加严格权限：仅代理账号本人可为自己店铺发起提现
