清理冗余的梯度返佣(TierCommission)配置

- 移除 Model 层：删除 ShopSeriesCommissionTier 模型及相关字段 - 更新 DTO：删除 TierCommissionConfig、TierEntry 类型及相关请求/响应字段 - 删除 Store 层：移除 ShopSeriesCommissionTierStore 及相关查询逻辑 - 简化 Service 层：删除梯度返佣处理逻辑，统计查询移除 tier_bonus 字段 - 数据库迁移：创建 000034_remove_tier_commission 移除相关表和字段 - 更新测试：移除梯度返佣相关测试用例，更新集成测试 - OpenAPI 文档：删除梯度返佣相关 schema 和枚举值 - 归档变更：归档 remove-tier-commission-redundancy 到 archive/2026-01-30- - 同步规范：更新 4 个主 specs，标记废弃功能并添加迁移指引原因：梯度返佣功能与一次性梯度佣金功能重复，且从未实现实际计算逻辑迁移：使用一次性佣金的梯度模式 (OneTimeCommissionConfig.type = "tiered") 替代
