feat: complete feedback and comment management

- Delete stub InterviewController (501-only endpoints)
- ConsoleFeedbackView: replace mock data with real fetchPendingFeedback API
- Add CommentAdminController (GET /api/v1/admin/comments)
- Add CommentService.listAllComments with batch user/article loading
- ConsoleCommentsView: real comment table with status filter and pagination
- Add comment-admin.js API module
