feat: update sentry settings for nextjs

[Alessandro100]

Summary:

Adjusted the settings so that Sentry is compatible with the new SSR / NextJs setup. Added source maps for easier error detection

Expected behavior:

If there is an unhandled error that occurs in the server, client, or edge function, it will be logged to Sentry. It will only be enabled on PROD environment
