时间框（flatpickr allowInput 的手输体验）
- flatpickr 把 <input type=datetime-local> 就地改成 type=text，原生分段编辑器被替换掉；
allowInput 又是「整串解析」语义：实测 parseDate('2026') 只出年份、'202666' 才出月份，
于是「年份很长才跳下一位」；'20260606' 还会被静默错解成 2030-12-06 且不报错。
- 新增 static/js/datetime-input.js：自定义 parseDate（纯数字只收 4/6/8/12/14 位，
歧义与非法日期一律拒）+ 输入引导（段满即补分隔符，敲完 4 位年份立刻跳月份位）。
按标准格式不做自动补零、不前滚；越界值原样保留交报错，不静默改成合法值。
- 三处页面（编辑/照片/专题）共用 attachPicker，配置与原先一致，模板净减 5 行。
弹窗
- window.prompt 会把提示文本与默认值写进地址栏并留进历史（confirm/alert 无此问题）。
- 新增 static/js/prompt-box.js 替代：原生 <dialog>.showModal()，遮罩/Esc/焦点齐全，
旧浏览器降级成页面顶部一条。已换 report.html 复制链接兜底与 edit.html 活动改名。
- 门禁 no_prompt_test.go：静态扫模板禁止 prompt(，并钉住 JS 与 CSS 都在。
统计脚本
- 原来只能改 conf/app.ini（要重启），现在后台「站点设置」可开关 + 填写，默认关闭。
- cleanTrackScript 挡住注入面：开闭 <script> 标签数不配平（提前闭合会让页面散架）、
src 的 javascript:/data: 伪协议、超长截断。注意不能用「出现 </script 就拒」当规则——
百度统计、Umami 贴的就是完整 HTML，正常用法会被挡死。
门禁
- datetime-input.test.js：34 条断言（node 直跑，无依赖）。
- TestCleanTrackScript：逐条边界 + 定义性不变量（任何输入都不得产出含 </script 的非空结果）。
- 三项均做过变异验证，改坏实现都会被对应测试抓到。
实测：真实站点逐键 2→20→202→2026-→2026-06-→2026-06-06T；
统计脚本六个场景（默认关/只填不开/开+URL/后台与登录页不挂/危险输入/关掉恢复）全部符合预期。
全量 internal/web 204 例 0 skip，其余包全绿，gofmt 干净。
