feat(accounts): 增加高价值资产一键筛选与高级自定义筛选功能

1. 后端新增高价值套装状态筛选（双套均可换/可换白日梦/可换萌兔/已拥有/高价值待救/未查资料），兼容 MySQL 原生 JSON 与 SQLite unicode 转义存储；
2. 后端新增多维资产与状态区间筛选（积分范围、鱼翅范围、宝典开通、电竞开通、角色绑定状态），并支持与批量打标签/删除联动；
3. 统计接口 accounts_summary 新增 high_value 聚合数据，毫秒级返回各类高价值资产数量；
4. 前端账号管理页面新增「高价值一键筛选」胶囊区（带数量徽标与激活状态，即点即滤）；
5. 前端新增可折叠「高级自定义筛选」面板，支持套装状态下拉、积分快捷区间（≥300、≥600）、鱼翅快捷区间（>0、≥6）、宝典与角色绑定状态多条件组合；
6. 补充 6 个高价值筛选与资产区间单元测试，全量用例通过。
