desk: add shortcodes [dw_til]/[dw_bookmarks]/[dw_recently_edited] (block-ready)

Wrap the echoing TIL/bookmarks helpers (ob_start) and the inline Recently-Edited
sticky loop from page-desk.php as shortcodes, so they can be dropped into block
content when the Desk sidebars migrate. No visual change yet — page-desk.php
still renders via the direct function calls.
