- Replaced all instances of the placeholder image path from "/static/images/placeholder.jpg" to "/static/images/replaceable_template_image.png". - Added a new Nginx location block for serving app data with a long cache expiration. - Enhanced the image generation service to return the new template image when generation fails. - Updated various services and endpoints to ensure consistent handling of asset paths, including resolving backend asset URLs. - Removed Electron-specific checks from several components to streamline API calls and improve compatibility with web deployments. - Improved error handling and logging in the PDF export process. - Adjusted Next.js configuration for API routing to ensure proper asset serving in Docker environments.
