fix(键盘): 统一修复 Android 软键盘遮挡输入框

根因: Tauri targetSdk 37 强制 edge-to-edge, MainActivity 不处理 IME Insets,
系统不再因键盘缩小窗口, 清单 adjustResize 失效, 键盘直接盖住 WebView。

- 新增 scripts/ci/android-softinput.sh: init 后注入 windowSoftInputMode=adjustResize,
  并重写 MainActivity.kt 监听 IME Insets, 键盘可见时把高度加到内容容器底部 (API 30+),
  让 WebView 真正变矮, 所有 bottom 弹层自动上移
- CI (android-build.yml) 与本地 build-apk.sh 在 init 之后、build 之前调用该脚本 (幂等)
- 新增全局 useKeepInputVisible: 输入框聚焦后用 scroll-into-view-if-needed 滚入可视区,
  覆盖页面滚动与 Popup 内部滚动
- 弹层补 max-height + 内部滚动, 防止键盘弹出后顶部被顶出屏幕
- calibrateSafeTop 在键盘弹出时保留旧值, 避免误判导致整页跳动
