Bulk actions for comments

Introduce essential bulk action capabilities within the comments section, significantly streamlining moderation workflows. This feature will allow users to select multiple comments simultaneously and apply actions such as:

1. Bulk Hide: Instantly hide a selection of comments from public view.

2. Bulk Delete: Permanently remove a selection of comments from the platform.

This enhancement provides critical efficiency for managing high volumes of comments, enabling rapid response to spam, irrelevant content, or widespread issues, and drastically reducing the manual effort required for maintaining a clean and controlled social media presence.
