重构: 店铺套餐分配系统从加价模式改为返佣模式

主要变更：
- 重构分配模型：从加价模式（pricing_mode/pricing_value）改为返佣模式（base_commission + tier_commission）
- 删除独立的 my_package 接口，统一到 /api/admin/packages（通过数据权限自动过滤）
- 新增批量分配和批量调价功能，支持事务和性能优化
- 新增配置版本管理，订单创建时锁定返佣配置
- 新增成本价历史记录，支持审计和纠纷处理
- 新增统计缓存系统（Redis + 异步任务），优化梯度返佣计算性能
- 删除冗余的梯度佣金独立 CRUD 接口（合并到分配配置中）
- 归档 3 个已完成的 OpenSpec changes 并同步 8 个新 capabilities 到 main specs

技术细节：
- 数据库迁移：000026_refactor_shop_package_allocation
- 新增 Store：AllocationConfigStore, PriceHistoryStore, CommissionStatsStore
- 新增 Service：BatchAllocationService, BatchPricingService, CommissionStatsService
- 新增异步任务：统计更新、定时同步、周期归档
- 测试覆盖：批量操作集成测试、梯度佣金 CRUD 清理验证

影响：
- API 变更：删除 4 个梯度 CRUD 接口（POST/GET/PUT/DELETE /:id/tiers）
- API 新增：批量分配、批量调价接口
- 数据模型：重构 shop_series_allocation 表结构
- 性能优化：批量操作使用 CreateInBatches，统计使用 Redis 缓存
