fix(packui): M113 收口 —— 导出的「Save to」字段形状与「没进包」标题承诺

复审看图挑出的两处，只改这两处，其余不动。

1. **Save to 字段**：原来是 `label("Save to (empty = suggested)")` + 空值，看起来像「这句提示就是字段值」，
   与上面 Pack name / Version 的「标签在上、值在下」不一致。改成短标签 `Save to` + 占位
   `empty = suggested path`（新增 `PackExportOutputPlaceholder` 一个键）。

2. **`Not in the pack (listed one by one)` 与 `...and 6 more files` 自相矛盾**：13 条没进包的其实全列了，
   但紧随其后的「还有 6 个」说的是**内联样例**的截断，两句挨着会被读成一件事。
   改法：「没进包」标题带真实计数（`Not in the pack: {count}`），内联样例加自己的标题
   `Copied into overrides/ (first {shown}):`，截断那句改成 `…and {count} more files (not shown here)`
   —— 谁被截断、截了几条，写在它自己的那一块里。

`tolerable_title` 因此改成收 `String`（计数是运行时 format 出来的），`golden.rs` 同步三个键。

门禁：`cargo fmt --all --check` 通过；`cargo test -p unlucky-app-iced --lib -j 2`
504 passed / 0 failed（TEST_EXIT=0）；`cargo check -p unlucky-app-iced --all-targets` 零 warning。
出图：`04-export-light.png` / `04-export-dark.png` 已重出（其余 8 张未受影响、未改动）。
