Summary of issue

The comment system lacked support for nested discussions (replies to comments) and required a moderation flow. Administrators needed the ability to review pending comments, understand their context within a thread, update their approval statuses, and forcefully remove inappropriate content.

Summary of change

Implemented nested comment replies and a complete administrative moderation suite.
Key changes:

• Replies implementation: added logic to build hierarchical comment trees in memory, allowing users to see comments with their nested replies sorted by date.
• Admin endpoints (CommentController):
  • GET /pending: gets a flat list of all comments awaiting moderation (CommentStatus.Pending), sorted from oldest to newest.
  • GET /withReplies/{id}: fetches a specific comment and its entire nested reply tree to provide context for moderation (ignores status filters).
  • PUT /updateStatus: allows admins to change a comment status (to Approved or Rejected).
  • DELETE /adminDelete/{id}: enables admins to delete any comment and its cascade of replies without ownership checks.
• Created corresponding commands, queries, handlers, and DTOs.
• Testing: added unit tests for all new handlers, validators, and the controller, covering tree building, sorting, and cascade deletion.
