fix: improve module config UX messaging and spacing (#1656)

- Move "Module configuration complete" to appear after all customization
  prompts finish, not just after defaults are applied
- Change spinner stop message to "Module defaults applied" for clarity
  when customization follows; keep "Module configuration complete" for
  express mode where no customization prompts follow
- Remove extra blank line before post-install notes
- Wrap spinner loop in try/finally for error safety
