<h4>Phase 6: Email Blast Integration + Global Fix</h4><h5>Email Blast PHPMailer Integration</h5><ul><li><strong>Dev SMTP redirect:</strong> On <code>.lcl</code> environment, Email Blast SMTP settings are overridden to use Mailtrap sandbox (configurable via MAILTRAP_HOST/PORT/USER/PASS constants). No bulk emails delivered from dev.</li><li><strong>Email logging:</strong> Every Email Blast send (success or failure) is now logged to <code>email_log</code> with <code>module_name='Email Blast'</code>, <code>template_code='email_blast'</code>, <code>provider='smtp'</code>. Logs include site context (siteid, sitelinkid).</li><li><strong>Mailtrap constants:</strong> Added MAILTRAP_HOST, MAILTRAP_PORT, MAILTRAP_USER, MAILTRAP_PASS to define_common.php (only defined on .lcl).</li></ul><h5>Global Fix</h5><ul><li><strong>Fixed:</strong> TypeError: Cannot read properties of undefined (reading 'replace') in toolbar.php getModuleNameFAQ — <code>data.ItemName</code> was undefined when FAQ module returned empty. Changed <code>||</code> to <code>&&</code> in null check and added top-level truthiness guard.</li></ul><h5>All Phases Complete</h5><table><tr><th>Phase</th><th>Status</th></tr><tr><td>1.
