- New dedicated Content Manager tab (WordPress-like layout) with: - Stats dashboard (published, drafts, categories, quizzes, attempts) - Sidebar with category tree and filter controls (status, category) - Table-style content list with search - Full-page editor with title bar, meta fields, body editor, quiz builder - Content Manager visible only for admin and moderator roles in sidebar - Removed CMS from admin panel (admin panel is admin-only again) - Email templates: fully responsive with max-width, proper mobile breakpoints, table-based layout for Outlook/Gmail compatibility, no overflow - Security: escape all user data in emails with escHtml(), escape APP_URL in verify-email HTML, replace raw err.message with generic errors in auth - Security: email body from admin settings now HTML-escaped before rendering
