CaIon 0c0ccf510b refactor: 抽象统一计费会话 BillingSession ...

将散落在多个文件中的预扣费/结算/退款逻辑抽象为统一的 BillingSession 生命周期管理：

- 新增 BillingSettler 接口 (relay/common/billing.go) 避免循环引用
- 新增 FundingSource 接口 + WalletFunding / SubscriptionFunding 实现 (service/funding_source.go)
- 新增 BillingSession 封装预扣/结算/退款原子操作 (service/billing_session.go)
- 新增 SettleBilling 统一结算辅助函数，替换各 handler 中的 quotaDelta 模式
- 重写 PreConsumeBilling 为 BillingSession 工厂入口
- controller/relay.go 退款守卫改用 BillingSession.Refund()

修复的 Bug：
- 令牌额度泄漏：PreConsumeTokenQuota 成功但 DecreaseUserQuota 失败时未回滚
- 订阅退款遗漏：FinalPreConsumedQuota=0 但 SubscriptionPreConsumed>0 时跳过退款
- 订阅多扣费：subConsume 强制为 1 但 FinalPreConsumedQuota 不同步
- 退款路径不统一：钱包/订阅退款逻辑现统一由 FundingSource.Refund 分派
