🎯 UX Improvements for PropChain FrontEnd

Overview

This pull request implements four comprehensive UX improvements for the PropChain FrontEnd project, addressing issues #145, #144, #142, and #143. These enhancements significantly improve user experience, accessibility, and educational value for Web3 users.

📋 Issues Addressed

✅ Issue #145: Drag-and-Drop Portfolio Reordering

Problem: Users couldn't customize their portfolio order, limiting personalization.

Solution: Implemented smooth drag-and-drop functionality with:

• DraggablePropertiesList Component: Full-featured drag-and-drop using HTML5 Drag and Drop API
• Visual Feedback: Hover states, drag indicators, and smooth animations
• Persistence: localStorage integration to save custom order across sessions
• Accessibility: Full keyboard navigation (arrow keys) and ARIA labels
• Reset Option: One-click restore to default ordering

Files Modified:

• src/components/dashboard/DraggablePropertiesList.tsx (new)
• src/components/dashboard/PropertiesList.tsx (updated)

✅ Issue #144: Web3 Terminology Tooltips

Problem: New users struggled with Web3 terminology like "gas fee", "token", "smart contract".

Solution: Comprehensive educational tooltip system:

• Web3Tooltip Component: Reusable tooltip with rich content
• 15+ Terms Covered: gas fee, token, smart contract, yield, APY, liquidity, slippage, block confirmation, blockchain, wallet, dApp, DeFi
• Contextual Help: Blue info icons with hover interactions
• Examples: Real-world examples for each term
• Mobile Friendly: Touch-optimized interactions

Files Modified:

• src/components/ui/Web3Tooltip.tsx (new)
• src/components/TransactionCard.tsx (enhanced)
• src/components/dashboard/PropertyCard.tsx (enhanced)

✅ Issue #142: Transaction Status Feedback

Problem: Users experienced anxiety during transaction processing due to lack of visibility.

Solution: Step-by-step transaction progress system:

• TransactionProgress Component: Modal with detailed progress tracking
• 4-Stage Process: Signing → Broadcasting → Confirming → Completed
• Real-time Updates: Live confirmation tracking (X/12 blocks)
• Error Handling: Retry mechanisms and clear error messages
• Visual Design: Professional modal with backdrop blur and smooth animations

Files Modified:

• src/components/TransactionProgress.tsx (new)
• Enhanced transaction flow integration

✅ Issue #143: Copy-to-Clipboard Functionality

Problem: Manual copy-paste was cumbersome for addresses, hashes, and sharing.

Solution: Comprehensive copy system:

• CopyButton Component: Multiple variants (icon, text, default)
• Specialized Components: CopyAddress, CopyTransactionHash, CopyShareLink
• Web Share API: Native mobile sharing with clipboard fallback
• Visual Feedback: Checkmark animations and toast notifications
• Strategic Placement: Copy buttons next to all critical data points

Files Modified:

• src/components/ui/CopyButton.tsx (new)
• src/components/WalletConnector.tsx (enhanced)
• src/components/TransactionCard.tsx (enhanced)
• src/components/dashboard/PropertyCard.tsx (enhanced)
