Netlify + Supabase Developer

I already have a working CRM/Billing Dashboard deployed on Netlify. Current Issue: * Data appears on one browser but not another. * Application currently stores data in Local Storage (jrmedia_v3). * Need migration to proper Supabase database storage. Requirements: 1. Fix data persistence issue. 2. Store all data in Supabase. 3. Add Login System. 4. Create 2 Roles: * Admin * Staff 5. Staff cannot permanently delete records. 6. Implement soft delete/trash system. 7. Ensure application works on all browsers and devices. 8. Test and verify deployment on Netlify. This is not a rebuild. Existing application already works and only requires professionalization and security improvements.
