refactor(数据库): 迁移持久层到 Ent 并清理 GORM
将仓储层/基础设施改为 Ent + 原生 SQL 执行路径，并移除 AutoMigrate 与 GORM 依赖。 重构内容包括： - 仓储层改用 Ent/SQL（含 usage_log/account 等复杂查询），统一错误映射 - 基础设施与 setup 初始化切换为 Ent + SQL migrations - 集成测试与 fixtures 迁移到 Ent 事务模型 - 清理遗留 GORM 模型/依赖，补充迁移与文档说明 - 增加根目录 Makefile 便于前后端编译 测试： - go test -tags unit ./... - go test -tags integration ./...
