Features

• Save QR Data: Accepts QR data via a REST API and stores it in a Supabase database.
• Display QR Data: Fetches and displays QR data in a user-friendly HTML template.
• Supabase Integration: Uses Supabase as the backend database for storing and retrieving data.
• Dynamic HTML Templates: Renders data dynamically using Flask's Jinja2 templating engine.
