Guard external TIL/bookmarks fetches against timeouts

inc/utils.php pulls TIL/bookmarks from davidawindham.com via simple_html_dom; when the
fetch times out file_get_html() returns false and ->find() fataled the page (white screen
on desk/archive). Added `if (!$html) return;` after all 20 direct file_get_html($url)
calls so a slow/unavailable source degrades gracefully instead of crashing.
