Replaces the plain textarea with a contenteditable div + full toolbar
(bold, italic, underline, H2/H3, paragraph, bullet/numbered lists, link,
YouTube embed) — same as the lesson editor.
Toolbar buttons use mousedown+preventDefault so selection is preserved
when clicking format buttons. Both editors share the same button wiring
via closest('.rte-group') rather than hardcoded element IDs.
