✨ feat: 重构首页Hero、导航菜单与页面布局统一

HomeHero:
- 重建每日推荐(左)+私人FM(右)双栏布局
- FM播放/暂停切换、不喜欢/下一首、背景流动动画、均衡器特效
- 修复FM数据获取(res.data.data双层结构)
- 歌单预加载改为hover懒加载避免502

导航优化:
- SearchBar顶部菜单: 首页/歌单/专辑/排行榜/MV/本地音乐
- 侧边栏隐藏MV和本地音乐(hideInSidebar)
- 修复搜索类型切换时失焦收起(@mousedown.prevent)

页面统一:
- 新建StickyTabPage通用布局组件(标题+吸顶tabs+内容slot)
- 歌单/专辑/MV/播客页面统一使用StickyTabPage重构
- CategorySelector第一项添加ml-0.5防scale裁切

播客优化:
- RadioCard简化去除订阅按钮、容忍radio为undefined
- 去除最近播放section、loadDashboard包含loadSubscribedRadios

i18n: 新碟上架→专辑(5语言)、新增fmTrash/fmNext(5语言)
