feat: add show_icons and truncate_paths options to [confirm]

The trash/delete/overwrite confirmation dialogs (icons added in #4096)
had no way to disable icons, and long file paths would hard word-wrap
onto a new line right after the icon since a path has no internal
spaces to break on cleanly.

Add two options under [confirm], both independently toggleable from the
existing [input] show_icons:

- show_icons (default true): skip the icon lookup for confirm dialogs.
- truncate_paths (default false): RTL-truncate each path with a leading
  "…" to fit the popup's configured width, instead of word-wrapping.
