Describe the issue

On the discussion forum statistics page, when there are no visible (non-deleted) threads/posts, no statistics rows are displayed, even if deleted posts exist.

Since the stats table includes a "Total Deleted Posts" column, deleted posts are tracked but not shown in this scenario.

Expected behavior

If deleted posts exist, the stats page should still display rows showing how many posts each user has deleted, even if there are no non-deleted threads/posts.

To Reproduce
Steps to reproduce the behavior:

1. Go to the Discussion Forum stats page (/forum/stats)
2. Ensure there are only deleted posts (no visible threads/posts)
3. Observe that no statistics rows are shown

Configuration

• OS: macOS
• Browser: Chrome

Screenshots

A screen recording is attached showing:

• the stats page when only deleted posts exist
• no statistics rows being displayed despite deleted posts being tracked

Additional context

Discussed with a maintainer, and it was noted that since deleted posts are tracked, they should likely be visible.
