## Description Currently certificate translations on production sometimes does not show the required language. This could not be replicated when creating certificates on staging (Browserless.io) and local development (Chromium), which means this fix ultimately cannot be tested unless on live. This is an attempt to fix it by isolating the certificate generation into it's own context, and applying a cookie to define the required language. This fix is based on the assumption that there is some sort of error which pushes the certificate to be generated on the client side, which ultimately will render in English due to constraints on nextjs. ## Changes Made - Apply language into cookie instead purely dynamically on SSR - Minor unrelated fixes ## Testing Performed Tested to ensure certificates could still be generated
