Incomplete Frontend Implementation

[Lynndabel]

Priority: 🟡 Medium
Files: Multiple frontend files
Issue: Frontend has placeholder implementations and TODO comments
Impact: Limited functionality, poor user experience
Labels: frontend, placeholder, functionality

Examples:

// frontend/lib/contract/products.ts:14-16
// TODO: Replace with actual contract call or indexer query
// For now, return empty array as placeholder

Files with incomplete implementations:

• Product registration forms (partial blockchain integration)
• Dashboard analytics (mock data handling)
• QR code generation (placeholder implementation)
