Pull request overview

This PR upgrades the tornado dependency from version 6.2 to 6.5.3 to address three security vulnerabilities identified by Snyk. Tornado is a transitive dependency required by flower (version 1.2.0), which is used for Celery monitoring in this Django application. The upgrade uses a minimum version constraint (>=6.5.3) to ensure the security fixes are present while allowing for future patch updates.

Key Changes:

• Adds explicit tornado version constraint (>=6.5.3) to requirements/base.txt as a pinned security fix
• Addresses three Snyk-identified vulnerabilities in tornado 6.2

This dependency addition should follow the existing organizational pattern in this file. All other dependencies are grouped under section headers with a separator line. Consider adding a section header for Tornado, such as:

This would maintain consistency with the existing structure where dependencies are organized by purpose or package name.
