Add Matomo analytics tracking with Suspense fix

- Created MatomoAnalytics component with page view and event tracking
- Fixed Next.js build issue by wrapping useSearchParams in Suspense
- Added tracking for user interactions:
  - Search functionality
  - Table sorting
  - Filter changes (material, finish, color)
  - Dark mode toggles
  - Admin login success/failure
  - Admin filament create/update actions
- Updated Amplify environment variables via AWS CLI
- Analytics URL: https://analytics.demirix.dev (Site ID: 7)
- Only loads when environment variables are set
