feat(supply-api): 完成核心模块实现
新增/修改内容： - config: 添加配置管理（config.example.yaml, config.go） - cache: 添加Redis缓存层（redis.go） - domain: 添加invariants不变量验证及测试 - middleware: 添加auth认证和idempotency幂等性中间件及测试 - repository: 添加完整数据访问层（account, package, settlement, idempotency, db） - sql: 添加幂等性表DDL脚本 代码覆盖： - auth middleware实现凭证边界验证 - idempotency middleware实现请求幂等性 - invariants实现业务不变量检查 - repository层实现完整的数据访问逻辑 关联issue: Round-1 R1-ISSUE-006 凭证边界硬门禁
