feat: Add comprehensive mobile responsiveness

Implemented complete mobile styling improvements for Scrapy UI:

- Mobile-responsive sidebar with hamburger menu (Sheet component)
  - Sidebar hidden on mobile, slides in from left as overlay
  - Auto-closes on navigation
- Mobile header with hamburger button, title, and theme toggle
- Layout switches from horizontal to vertical flexbox on mobile
- Reduced container padding on mobile (p-4 vs p-6)
- All tables wrapped in horizontal scroll containers
- Added whitespace-nowrap to prevent text wrapping in table cells
- Optimized all dialogs for mobile:
  - Responsive width: max-w-[95vw] on mobile, max-w-[425px] on desktop
  - Full-width buttons on mobile
  - Proper gap spacing in footers
  - Text wrapping for long content (break-all for Job IDs)
- Dashboard cards already responsive with grid breakpoints

App now works flawlessly on mobile devices!
