## Summary by CodeRabbit

* **Refactor**
  * Removed the comment feature flag from the application.
* The ability to enable comments now depends solely on server
configuration, not on a feature flag.
* **Chores**
* Cleaned up related feature flag definitions and internal logic for
comment enablement.
