fix(comments): open the action dropdown with theme-owned delegation

The comment three-dot menu relied on the legacy data-toggle=dropdown
delegation living in comment-move-form.js; when that bundle chain does
not evaluate (stale cache or an earlier top-level error), the menu
appears dead. Move the comment action dropdown to its own top-level
document delegation in comments.js (data-aksrt-comment-drop), keep the
.open-driven CSS contract including the mobile drop-fixed-sm sheet,
sync aria-expanded, close on outside click / Escape / menu item click,
and stay idempotent for AJAX-injected comments.
