Desktop files: Cascade-trash comment shortcuts when a comment is trashed

[CookieDarb]

What?

Closes #1012

Fixes the bug where comment shortcuts placed on the desktop wallpaper remain visible on the desktop instead of being moved to the Recycle Bin when the comment is trashed.

Why?

Desktop shortcuts for entities (posts, attachments, users) automatically cascade-trash their placements when the underlying entity is removed or moved to the trash. Comments had a registered desktop file type (OpenStation_Comment_File), but cascade-cleanup.php lacked hooks for comments. As a result, trashing a comment left its desktop shortcut active on the wallpaper, and the shortcut was never routed to the Recycle Bin.

How?

• includes/desktop-files/cascade-cleanup.php:
  • Added openstation_files_cascade_on_comment_trash( $comment_id ) to soft-trash placement rows where file_type='comment'.
  • Hooked WordPress Core's trashed_comment and deleted_comment actions to cascade comment trashing and permanent deletions to their desktop shortcuts.
• tests/phpunit/tests/desktopFilesCascadeCleanup.php:
  • Added test_wp_trash_comment_triggers_cascade() to assert that calling wp_trash_comment() soft-trashes matching comment placements.
  • Added test_delete_comment_triggers_cascade() to assert that calling wp_delete_comment() soft-trashes matching comment placements.

Testing Instructions

1. Place a comment shortcut onto the desktop wallpaper.
2. Move the comment to the Trash.
3. Return to the desktop wallpaper and verify that the comment shortcut is no longer on the active desktop.
4. Open the Recycle Bin app and check the Desktop list to confirm the comment shortcut was moved there.
