/**
 * OpenStation — Native Comments Window: capability gates.
 *
 * Multi-tier gating, parallel to WordPress core's
 * `edit-comments.php` flow:
 *
 *   - `edit_posts`     → REGISTER the window. The cheapest classic-admin
 *                        cap that gates "can read the comments screen"
 *                        for any author (their own comments). The REST
 *                        controller does per-row checks.
 *   - `moderate_comments`
 *                      → bulk approve / unapprove / spam / trash actions
 *                        and the global Pending tab badge.
 *   - `edit_comment`   → edit a comment's text (per-target, server-checked).
 *
 * UI-side gating is purely UX polish — the REST routes in `rest.php`
 * re-validate every cap and every per-target permission before
 * mutating anything.
