README: replace Unicode box chars in UI preview with plain ASCII

The installer UI preview in README.md contained Unicode box-drawing
characters (╔╗╚╝║═) and bullets (●○✓) from an earlier draft that
didn't match the actual script output. Replaced with the current
plain-ASCII UI output that the script actually renders.

Also replaced em-dashes (—) with -- outside of code blocks for
consistency with the rest of the documentation.
