Temporarily disable ECM integration to prevent fatal errors

- Added ECM integration toggle for easy enable/disable
- Temporarily disabled ECM integration to prevent fatal errors
- Added debugging logs to track ECM files path resolution
- PDF saving to disk still works without ECM integration
- Declaration validation will work without document management
- Can be re-enabled once ECM files path is properly resolved
