[IMP] mass_mailing_sms: improve list view of SMS marketing

This commit improves the list view of SMS Marketing to make it
similar to Email Marketing. Now we have these fields in following
order:

- calendar_date
- subject (string updated to `Title`)
- mailing_model_id (optional hide)
- user_id
- campaign_id (optional hide, displayed when activated)
- ab_testing_enabled (displayed when activated)
- sent (added sum)
- clicked (updated string to `Clicked (%)` and added progressbar widget, average)
- bounced (updated string to `Bounced (%)`, optional hide with progressbar widget
  and average)
- state
