Subject: [PATCH] Refactor TemplatePreviewController to enhance template
 retrieval and default data handling: Updated the preview method to fetch
 template objects by ID, introduced default data management, and replaced
 placeholders with default values using TemplateService. Improved method
 signatures for clarity and consistency in data handling.
