- Add Vertex AI provider (Gemini models via @google-cloud/vertexai SDK)
- Add LiteLLM proxy support (OpenAI-compatible, routes to any provider)
- Admin panel: model search/discover from provider API, enable/disable, custom models, set default
- New endpoints: /config/models/discover, /config/models/add-discovered, /config/models/default
- Updated models.js with VERTEX_MODELS and LITELLM_MODELS lists
- Updated health endpoint with vertex + litellm status
The admin model management (enable/disable, custom models, default override)
had persistent rendering issues. Removed the UI panel — models are managed
via the global model selector in the header, which works reliably. Backend
API endpoints for model config are retained for future use.
- Full model management UI in admin panel: toggle models on/off, add custom
model IDs (any OpenRouter/Bedrock ID), set admin-configured default model
- /api/models now returns admin-set default model, frontend respects it
- Toggle switch CSS for clean enable/disable UX
- Backend already had the API endpoints, this adds the missing UI
- 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
