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。
