Show install summary when configuration is valid (#4475)

* Show install summary when configuration is valid

Previously the Install menu preview was empty when everything was valid,
leaving the user with no "ready" signal. Now show "Ready to install"
plus a two-column summary of the current configuration.

- New _install_summary() composes an aligned key/value table with rows
  for disks+FS+LUKS, bootloader, kernel, profile, greeter, package
  count, network, locale and timezone. Column width adapts to the
  longest translated label so translations keep the alignment.
- Rows whose underlying config is not set are skipped rather than
  rendered as empty.
- base.pot / uk base.po: add new msgids for summary labels.

* Move install summary into ConfigurationOutput

The summary helper that renders the install preview's two-column
configuration overview lived in GlobalMenu. Move it to
ConfigurationOutput.as_summary() so it sits alongside the JSON
output methods that share the same role. The preview now syncs
menu state to ArchConfig and delegates rendering.
