feat: Create Client Dashboard UI

[legend4tech]

Client Dashboard Implementation

Description

Implemented a comprehensive client dashboard for the TaskChain platform following the established design system and principles. The dashboard provides clients with complete project management, milestone tracking, approval workflows, and dispute resolution capabilities.

How It Was Solved

• Analyzed existing design patterns from hero, features, and component files to maintain consistency
• Created modular components following the glass morphism design system with backdrop-blur effects and gradient borders
• Implemented state management for project operations, approvals, and disputes
• Built responsive layouts using Tailwind flexbox with mobile-first approach
• Integrated Lucide React icons and semantic HTML for accessibility

Components Created
