erio	df57d2776b	fix(billing): reject rate_multiplier <= 0 on save; clamp negatives to 0 in compute ... 分组倍率和用户专属倍率在保存时没有校验，0 会触发计费层的 `<=0 → 1.0` 防御条款，结果订阅/余额分组按标准价扣费；完全是沉默地绕过了业务规则。 - 保存校验（admin_service）：CreateGroup / UpdateGroup / BatchSetGroupRateMultipliers / UpdateUser.SyncUserGroupRates 全部要求 > 0 - 计算层（billing_service）：三处 `<=0 → 1.0` 改为 `<0 → 0`；负数按 0 结算， 避免配置异常被静默按 1x 收费 - 前端：分组倍率 / 用户专属倍率输入 min 统一到 0.001 - 删除未使用的 IsFreeSubscription 方法 测试：新增 billing_service_rate_multiplier_test.go 端到端验证；更新原有锁定 旧 `<=0 → 1.0` 行为的测试。	2026-04-17 22:06:32 +08:00
