GHSA-pm8c-3qq3-72w7: phpMyFAQ has SQL Injection in CurrentUser::setTokenData through unescaped OAuth token fields

CurrentUser::setTokenData() in phpmyfaq/src/phpMyFAQ/User/CurrentUser.php at lines 515-534 builds a SQL UPDATE statement with sprintf and interpolates OAuth token fields (refresh_token, access_token, code_verifier, and json_encode($token['jwt'])) without calling $db->escape(). Sibling methods setAuthSource() and setRememberMe() in the same file do call $db->escape() on user-controlled values, so the omission is local to this method. An attacker (Bob) whose Azure AD display name contains a single quote (for example O'Brien, or a deliberate SQL payload) breaks out of the string literal and injects arbitrary SQL against the phpMyFAQ database.
