feat(frontend): improve error handling and UX - Sprint 3 Story 4

Add comprehensive error handling with Error Boundary and improve user feedback. Changes: - Created global ErrorBoundary component with fallback UI using react-error-boundary - Integrated ErrorBoundary in root layout to catch all errors - Created Loading component with variants (sm, md, lg) for consistent loading states - Created EmptyState component for better empty data display with CTAs - Improved form error messages in login and register pages (consistent destructive styling) - Updated projects page to use EmptyState component - Added better error handling with retry actions UX improvements: - Better error messages and recovery options with clear action buttons - Consistent loading indicators across all pages - Helpful empty states with clear descriptions and CTAs - Graceful error handling without crashes - Consistent destructive color theme for all error messages Technical: - Installed react-error-boundary package (v5) - All TypeScript types are properly defined - Build and type checking pass successfully 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
