Subject: [PATCH] fix(master-dashboard): Resolve trainers table AJAX loading
 error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Initialize HVAC_Master_Dashboard_Data during plugin init to ensure
  AJAX handler is registered for all requests (not just template loads)
- Accept both hvac_ajax_nonce and hvac_master_dashboard_nonce for
  backward compatibility with existing JavaScript
