[Konsole] Improve the appearance and utility of tabs

Default behavior is really confusing for programs with the same name :person_facepalming:.

Settings > Configure Konsole > Tab Bar / Splitters > Expand individual tab widths to full window

Settings > Edit current profile > Tabs > Tab title format: %w

Outcome is neat :sparkles:.

If you double-click each individual tab you can change that setting per tab basis :person_shrugging:.
