feat(player/admin/api): 站内邮箱、在线状态、员工菜单权限与内容管理增强

API:
- 新增 player-messages 域：充值审核通过/拒绝、Banner/公告推广消息，支持多语言模板
- 新增 presence 域：Redis 心跳在线状态，管理端可查询在线玩家数
- User 表增加 visible_menus 字段；新增 player_messages 表及迁移
- 充值审核通过/拒绝时按系统配置自动写入玩家站内消息
- 管理端新增 GET /deposit-orders/pending-count、GET /presence/online-count
- 玩家端新增消息 CRUD、presence/ping、home 返回 inbox 开关配置
- 员工管理支持 visibleMenus 配置与删除保护（不能删自己/最后超管）
- SystemConfig 增加 inbox 功能开关及各类通知开关

Admin:
- 员工管理：按角色默认菜单 + 可勾选可见菜单项
- ManageLayout：按 visibleMenus 过滤侧栏；充值待审数量角标轮询
- Contents：富文本编辑器、图片字段组件重构
- DashboardPlayers：展示在线玩家数；AdminPlayerStatusCell 在线状态列
- 多页面 i18n 与权限细节调整

Player:
- 站内邮箱中心（InboxHub）：消息列表/详情、未读角标、一键已读/删除
- 公告列表与详情页；走马灯可跳转详情
- 客服 Modal 改为 Panel，与邮箱 Hub 整合
- 充值状态轮询通知；presence 心跳；BetSlip 清空二次确认
- HomeView 今日赛事板块；FootballView 等体验优化

Shared: 新增 CANNOT_DELETE_SELF、STAFF_NOT_FOUND、MESSAGE_NOT_FOUND 等错误码
Docs: 玩家端缺失功能分析文档
Chore: 移除 .agents/skills 设计类 skill 文件
