Enrich lesson comments: Markdown formatting, edit, higher limit

Add a formatting toolbar + safe Markdown rendering (react-markdown +
rehype-sanitize), raise the length limit 2000 -> 10000, and let authors
edit their own comments (new editComment action + editedAt column shown
as an 'изменено' badge).
