feat: 新增发布日期自选、站点 Logo、回收站清空等十项改进

- 编辑页标题改 filled 变体；标签改 tags 选择器（可勾选既有/输入新建）
- 笔记发布日期可自选（schema v2 新增 published_at 并回填），前台展示发布日期
- 登录页移除「请输入管理密码以继续」「连续失败将被暂时锁定」文案
- 站点设置每页条数收敛为 10/20/30/50 选择器，后端白名单同源校验
- 站点设置两卡片宽屏左右/窄屏上下；修改密码按钮改常规大小
- 后台各页顶栏固定高度，切换页面不再抖动
- 站点 Logo：settings 新增 site_logo（站内路径），gc/孤儿清单豁免 Logo 图片，
  博客 header 站点名前展示，设置页支持上传/更换/清除
- 回收站右上角一键清空（DELETE /api/admin/trash，含确认弹窗）
- pn init 写入 Markdown 语法示例文档（slug welcome，公开）与程序生成的示例图片
