Comments: Update the Mine count after AJAX actions

[ArkaPrabhaChowdhury]

Trac ticket: https://core.trac.wordpress.org/ticket/46017

Summary

• Updates the "Mine" comment count after replying to a comment through AJAX.
• Adds current-user ownership metadata to comment moderation AJAX responses.
• Uses the existing approved and pending deltas to update "Mine" only when the affected comment belongs to the current user.
• Adds regression coverage for the ownership metadata.

Why

The comments screen already updates the All, Pending, Approved, Spam, and Trash counts after AJAX actions, but it does not update Mine. Moderation responses also did not expose enough information for the client to know whether the affected comment belonged to the current user.

Testing

• npm run test:php -- --group ajax --filter "Tests_Ajax_wpAjax(DeleteComment|DimComment|ReplytoComment)" (18 tests, 132 assertions)
• npm run test:php -- --group ajax --filter Tests_Ajax_wpAjaxDeleteComment (6 tests, 85 assertions)
• PHPCBF and PHPCS with phpcs.xml.dist on both touched PHP files
• JavaScript JSHint passed for src/js/_enqueues/admin/edit-comments.js

Pull request overview

This PR improves the wp-admin Comments screen’s live counter updates by ensuring the “Mine” view count stays accurate after AJAX moderation and reply actions, using new server-provided metadata to determine whether a comment belongs to the current user.

Changes:

• Adds supplemental.is_current_user to _wp_ajax_delete_comment_response() so the client can detect ownership.
• Updates edit-comments.js to increment/decrement the “Mine” count after applicable AJAX actions.
• Adds PHPUnit regression coverage verifying the new ownership metadata in the AJAX response.
