freefire 4f3f3a265c feat: 友链/书库/移动端导航/排行榜等多模块功能
新增模块:
- 友链(friendlink)后端处理 + 前端管理页与友链板
- 书库(library):导入、章节、封面、阅读页、横竖版自适应 AdaptiveCoverSlot
- 顶栏导航(header_nav)配置与 MobileTabBar/MobileRailDrawers 移动端抽屉
- 排行榜 service 测试、站点页面测试、时间线发布(timeline_release)

其它改动:
- 后端 handlers/services 全量小幅调整
- 前端组件、库函数、URL/品牌/站点 URL 工具更新
- Lightbox 图片、MdEntries 条目卡、coverColor 派生色相等前端能力
