fix(editor): polish setup wizard + main-window narrow-width layout

- Setup wizard: de-box the title beside the logo; footer buttons size to
  content and sit together on one row (Refresh no longer stretches
  full-width and overflows); rename the deps-step "Done" button to "Next".
- Client Configuration dialog: show the count + only failures + next step
  instead of enumerating every successfully configured client.
- Main window header: version pill never shrinks/clips (flex-shrink 0);
  title stays at natural width.
- Tabs: flex-shrink so all six stay reachable when docked narrow.
- Connection status label wraps/shrinks instead of sliding under the
  Disconnect button (scoped to #connection-section).
