feat: 金额 decimal 精确计费、failover 按失败类型封顶、渠道小时桶预聚合、分层守护测试

- 计费:19 个金额字段 float64→decimal.Decimal,DB 列保持 numeric(20,8) 零迁移;
  API 金额仍为 JSON number(MarshalJSONWithoutQuotes),前端零改动
- failover:保留时间预算,新增 OT_PROXY_FAILOVER_CAPS_NET/SERVER/RATE/QUOTA
  按失败类型封顶换渠道次数(429/配额类瞬时失败时间预算形同虚设)
- 预聚合:新增 usage_channel_hourlies(schema v10),记账事务内同步 upsert,
  长窗口渠道统计走桶不再扫明细,spent_last_30d 改扫 usage_daily,v10 一次性回填幂等
- 守护:internal/arch_test.go 用 go/parser 强制分层依赖(fail-closed)
