Comments: Update the "Mine" count after AJAX moderation and reply actions.

[ikamal7]

Summary

• The comments list table updates the All, Approved, Pending, Spam, and Trash counts via AJAX after replying to or moderating a comment, but the "Mine" count never updates.
• Adds an isCurrentUserComment flag to the supplemental data returned by _wp_ajax_delete_comment_response() (used by both wp_ajax_delete_comment() for trash/untrash/spam/unspam/delete, and wp_ajax_dim_comment() for approve/unapprove).
• edit-comments.js uses that flag to bump span.mine-count by the same delta as Pending/Approved when the affected comment belongs to the current user, and unconditionally bumps it by 1 after a reply is added (a reply is always authored by the current user).

Why

"Mine" (class-wp-comments-list-table.php) counts comments where comment->user_id === get_current_user_id(), independent of moderation. Approve/Unapprove alone never changes this count since Mine already includes both pending and approved comments; only entering/leaving Spam/Trash does — which is what the JS change reflects.

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

Testing

• php -l on the touched PHP file.
• node --check on the touched JS file.
• Manually verified in the browser: replying to and moderating (approve/unapprove/spam/unspam/trash/untrash) a comment authored by the current user updates the "Mine" tab count; actions on other users' comments leave it unchanged.

Test plan

• Visit /wp-admin/edit-comments.php as a user who has authored comments.
• Reply to one of your own comments — "Mine" count increments.
• Approve/Unapprove one of your own comments — "Mine" count stays the same (comment just moves between Pending/Approved).
• Spam, Trash, and their Undo actions on your own comments — "Mine" count decrements/increments accordingly.
• Moderate a comment authored by a different user — "Mine" count does not change.
