Update CORS settings, enhance API URL detection, and improve template rendering

- Added new CORS origins for local development and specific IP addresses in `settings.py`.
- Refactored API URL retrieval logic in `loadSiteDefinition.ts` and `fileAccess.ts` to auto-detect based on the current origin.
- Enhanced error handling in API calls and improved logging for better debugging.
- Updated `renderTemplate` function to support additional block types and improved rendering logic for various components in `templateEngine.tsx`.
