feat: Add comprehensive payment analytics and fix external link paste

🎯 Payment Analytics Dashboard:
- Add 5 new payment analytics widgets for admin dashboard
- Unfunded tokens: logged-out users (localStorage tracking)
- Unfunded tokens: logged-in users without subscriptions
- Funded token allocations (backed by real subscriptions)
- Total subscription revenue with accurate billing cycle logic
- Total writer payouts from completed token payouts

🔧 Platform Fee Revenue Fix:
- Fix platform fee calculation to use gross amount (not net)
- Correct 7% calculation: gross = net / (1 - totalFeeRate)
- Account for Stripe fees in reverse calculation
- More accurate platform revenue reporting

📊 Data Pipeline Improvements:
- Cross-reference token allocations with subscription status
- Validate subscription active periods at allocation time
- Accurate billing period overlap calculations
- Proper token classification (funded vs unfunded)

🔗 External Link Paste Fix:
- Fix paste functionality in external link modal
- Add proper focus management for external URL input
- Prevent paste events from bubbling to editor
- Enhanced tab switching with auto-focus

🎨 UI/UX Enhancements:
- Consistent color coding for payment widgets
- Loading states and error handling
- Responsive design for all screen sizes
- Real-time data with debounced API calls

All payment analytics are now mathematically accurate and provide comprehensive financial insights for WeWrite's token economy.
