[charlottewiltshire0]

Integrate Sentry into the project for error tracking and monitoring. Ensure that the integration does not interfere with the build process on Cloudflare Pages.

Acceptance Criteria:

1. Add Sentry to the project for capturing and reporting errors.
2. Ensure the integration does not break the Cloudflare Pages build process.
3. Configure Sentry to work seamlessly with the deployment environment.
4. Test error reporting functionality to verify that errors are correctly sent to Sentry.
5. Provide a fallback mechanism or graceful handling if Sentry fails to initialize.
