fix: seeders-first default, compact footer, and folder-editor input isolation

Restore the seeders-desc default ordering that the new sort feature dropped,
so the healthiest torrents stay on top until `s` is pressed. Trim the
contextual footer (terse labels, folder key in the `?` overlay only) so the
added sort and folder keys never wrap it past one line. Gate the
download-folder editor on its own `editingFolder` flag instead of the shared
capture state, fixing the leak where `?`, `q`, and `m` fired through while
typing a path.
