reply is used as a noun and verb (button)

[audrasjb]

To be clear, what is needed here is a context for translators, using the _x() function.

## Summary

Fixes the ambiguous translation of the string 'Reply' used as a button/link label in comments UI. In some languages (e.g., German), "Reply" as a noun and as an imperative verb translate differently. Without a translator context, GlotPress cannot distinguish between uses, leading to mistranslations.

Replaces all __( 'Reply' ) occurrences with _x( 'Reply', 'verb' ) and adds /* translators: */ docblock comments, consistent with the existing pattern used for _x( 'Spam', 'verb' ) in the same codebase.

## Changes

• src/wp-admin/includes/dashboard.php — Use _x() for Reply button in dashboard comment actions.
• src/wp-admin/includes/class-wp-comments-list-table.php — Use _x() for Reply button in comments list table row actions.
• src/wp-includes/comment-template.php — Use _x() for default reply_text in get_comment_reply_link().
• src/js/_enqueues/admin/edit-comments.js — Expose wp.i18n._x alongside wp.i18n.__, and use _x() for both Reply button text assignments.

## Testing

1. Verify the comments admin screens (/wp-admin/edit-comments.php) still show "Reply" buttons correctly.
2. Verify the comment reply link renders correctly on the front end.
3. Verify the dashboard Recent Comments widget still shows a "Reply" action link.
4. Optionally: confirm the new verb context appears in GlotPress under the wp/dev project strings for 'Reply'.

Removing commit.
This needs to be also fixed on Gutenberg's side, too.
