feat: 商品推荐维度映射 + 复购提醒 + 供应商/规格迁移补全

- 修复 DatabaseInitializer 缩进与多余括号导致编译失败
- 迁移80: 创建 product_dimension_mapping 表 + 索引
- 迁移81: products 表添加 recommendation_tags/purchase_count_threshold/repurchase_interval_days
- 迁移82: 创建 repurchase_reminder_record 表
- 迁移83: 创建 repurchase_reminder_config 表
- 新增 ProductDimensionMapping/RepurchaseReminderConfig/RepurchaseReminderRecord 实体+Mapper
- schema.sql 同步新表DDL
- 小程序: DimensionProductList 组件 + api.js 推荐/复购接口
- 修复 RecommendationQuery DTO
