feat(board): remove live widget preview, streamline integration editing

- Drop the narrow live preview panel from the widget picker (it kept
  rendering oversized widgets with errors) along with its translations
- The Edit integration tab now opens the connection editor directly when
  a widget has exactly one integration
- The connection editor closes on outside click
- Keep the save/cancel footer floating at the bottom of the editor
