v1.1.1

Changed

• Admin activity log moved from the bottom of the recipients page into a modal overlay.
  A "Logs" button in the action bar (next to "Add recipient" and "Log out") opens the
  overlay; it can be closed with the × button, a click on the backdrop, or the Escape
  key. The overlay is 85 % of the viewport width and scrolls vertically when the log
  contains more entries than fit on screen, with the column header remaining sticky.
• Unsubscribe events are now recorded in the activity log (unsubscribed event) when a
  recipient removes themselves via the unsubscribe link.
