Add sample lab reports + “Use demo data” toggle for easier testing #165
Description
Is your feature request related to a problem or challenge?
Currently, new contributors/testers must upload their own lab reports to test the system. This raises privacy concerns and makes onboarding harder.
Describe the solution you'd like
Add a set of sample lab report images and a “Use demo data” toggle on the upload/landing page. When selected, it should load and parse demo reports (instead of requiring user-uploaded files).
Describe alternatives you've considered
1.Using dummy text data (but images are more realistic for OCR testing).
2.Sharing screenshots instead of real reports (less interactive).
Additional context
Store sample reports in /assets/sample_reports/ with a samples.json file for metadata.
Update the README with instructions on how to use demo data.
This will help newcomers quickly try the project without needing personal data.
