Description

Implements Issue #316: Conduct a comprehensive mobile responsiveness audit and fix all issues across the frontend.

Features

• Added a mobile-friendly hamburger menu for seamless navigation on small screens
• Refactored the dashboard and landing page grids to use responsive column stacking
• Optimized the milestone creation form with mobile-first flexbox layouts
• Ensured touch targets are appropriately sized and action buttons span the full width on mobile devices
• Made the Dispute modal and Explorer filters properly wrapped to prevent horizontal overflow

Tech Stack

• Next.js and React
• Tailwind CSS for mobile-first utility classes and responsive breakpoints
• Vanilla React state for the mobile menu toggle logic
• Responsive flexbox and CSS grids (flex-col sm:flex-row, grid-cols-1 sm:grid-cols-3)

Testing

1. Clone branch feature/issue-316-mobile-responsive-audit
2. cd frontend && npm install
3. Configure .env from .env.example
4. npm run dev and test on mobile viewports (e.g., using Chrome DevTools Device Mode)

Closes #205

⚠️ CI Workflow Action Required

Because of GitHub token workflow scope restrictions, I could not include the updates to .github/workflows/ci.yml in this PR directly. Please manually apply these two fixes to .github/workflows/ci.yml before merging so that the CI passes:

1. Frontend Lint Job (ci.yml line ~86): Add ESLINT_USE_FLAT_CONFIG: 'false' to the env vars to prevent Next.js 14 and ESLint 9 conflict.

   - name: Lint
     run: cd frontend && npm run lint
     env:
       NEXT_PUBLIC_API_URL: http://localhost:3001
       ESLINT_USE_FLAT_CONFIG: 'false'

2. Bundle Analysis Job (ci.yml line ~107): Change npm run analyze to npm run build since the bundle analyzer plugin is not installed.

   - name: Build with bundle analyzer
     run: cd frontend && npm run build
     env:
       NEXT_PUBLIC_API_URL: http://localhost:3001
