fix: 系统性修复安全问题、性能问题和错误处理

Browse Source 
安全问题修复:
- X-Forwarded-For越界检查(auth.go)
- checkTokenStatus Context参数传递(auth.go)
- Type Assertion安全检查(auth.go)

性能问题修复:
- TokenCache过期清理机制
- BruteForceProtection过期清理
- InMemoryIdempotencyStore过期清理

错误处理修复:
- AuditStore.Emit返回error
- domain层emitAudit辅助方法
- List方法返回空slice而非nil
- 金额/价格负数验证

架构一致性:
- 统一使用model.RoleHierarchyLevels

新增功能:
- Alert API完整实现(CRUD+Resolve)
- pkg/error错误码集中管理
