RfC447 - cannot delete sole patient case during registration process * consequence is patient cannot be found on registration search but also cannot be re-registered if it has an nhs number * can now only edit sole patient case, delete option only available for multiple patient cases
adaptations for request form access by non-logged-in user * generate 'centre' token in login() for use in request-form url * adapt create_form_tokens() to accept 'centre' only * Local::Utils encrypt & decrypt functions capture Crypt::CBC errors & return empty not stacktrace
