 {{{
 #!CommitTicketReference repository="" revision="48340"
 Accessibility: Administration: Improve the sortable postboxes areas on the
 Dashboard and Classic Editor pages.

 - makes the postboxes areas in the Dashboard visible also on large screens
 - uses a more meaningful text when all postboxes areas are empty instead
 of "Drag boxes here"
 - restores the ability to drag boxes to the "advanced" area in the Classic
 Editor page
 - makes the postboxes areas in the Classic Editor page visible while
 dragging so that users have a clue what the available areas are
 - improves the color contrast of the postboxes areas while dragging
 - uses `wp.i18n` for translatable strings in `wp-admin/js/postbox.js`

 Props xkon, karmatosed, audrasjb, ocean90, joedolson, afercia, azaozz.
 See #20491.
 Fixes #49288, #47541.
