Problem

Use Case pages reference EasyInvoice with incorrect URL (easy-invoice-demo.vercel.app) instead of the live production URL (easyinvoice.request.network).

Proposed Solution

Update all references across 6 Use Case pages:

• Change all URLs to https://easyinvoice.request.network
• Update Integration Approaches sections with correct links
• Ensure messaging aligns with "EasyInvoice as API showcase" strategy (from Oct 8 Tech Daily meeting)

Considerations

• Verify EasyInvoice URL is live and working: ✅ Confirmed
• Update all 6 use case pages: invoicing, payouts, payroll, checkout, subscriptions, payment-detection
• Remove any claims about features that don't exist (e.g., "custom domain support")
• Ensure consistent branding and messaging
