第九轮(部分)：修复日报徽章配色、彻底重做PIN定位方案、清理静态文件品牌残留

- 日报卡片"已提交/未提交"状态徽章补色：DailyReportCard用<article><header><em>结构，原选择器
  要求.report-cards直接子<button>，日报卡片永远命中不了、只落到不分状态的兜底样式；月报因为
  行本身就是<button>所以没受影响。详情页.report-author em同理补了区分色（原来恒为绿色，"未
  提交"用绿色在语义上很怪）。
- 青少年模式/独立密码设置的PIN输入定位改用结构性方案，不再靠猜一个rem偏移量：给
  .auth-pin-boxes/.auth-pin-input包一层.auth-pin-wrap，输入框inset:0精确覆盖方块的真实
  渲染框，不管外层页面有没有标题、padding多少都自动对齐。上一轮的补丁（.youth-password-gate
  .auth-pin-input{top:1.75rem}）把重叠率从0%提到32.5%，本轮实测确认还是不够（方块下方
  67.5%的面积点不中），根治后4个采样点（四角+中心）全部精确命中输入框。过程中额外发现并
  修复了两个更隐蔽的层叠问题：全局input[type=text]的height:2.5rem特异度反超裸class、
  textarea/input共享的margin:0.25rem重置——不清掉这两个会让inset:0看起来生效了、实际尺寸/
  位置还是被悄悄改掉。
- .report-loading（举报原因页加载态）补基础样式，原来在base.css里零匹配，吃浏览器默认<p>样式。
- 清理静态文件里的Tinode品牌残留：index.html/index-dev.html的<meta>标签（application-name/
  description/og:*/canonical，此前只改了<title>，meta标签一直没跟上）、manifest.json（name/
  short_name/description改MeetingIM；prefer_related_applications+related_applications整个
  删掉——这两个字段会让Android/Chrome"添加到主屏幕"时引导用户去装无关的第三方开源Tinode App，
  不只是文案问题）；删除.well-known/assetlinks.json（声明了无关第三方App对本域名的URL处理/
  登录凭据代理权限，属于遗留模板残留，无真实对应关系，直接移除而非编造虚假内容）。

manifest.json里的图标文件(logo96.png/logo192.png/logo.svg)本身画的就是Tinode的蓝绿橙"t"标志，
是真实的视觉品牌泄漏，但重新设计一套图标涉及视觉识别决策，本次未动，留给用户决定。
