Implement full comments system: domain entities (Comment, CommentLike), value objects (CommentContent), use cases (CRUD, like toggle), SQLAlchemy repository, API v1 endpoints, web UI with comment form and nested replies, i18n translations (EN/RU/FR/DE), and E2E tests. Fix nested reply (reply-to-reply) not displaying — the flat reply_comments dict was only queried for top-level comment IDs, so deeply nested replies were saved to DB (incrementing comment count) but never rendered. Switch to a recursive Jinja2 macro that renders any nesting depth.
