Missing restriction on string size of Full Name at https://demo.weblate.org/accounts/register/

Hi there #Vulnerability Title: >During my regular testing, I have found that there was no restriction on the amount of text that can be inserted into a user's Full name field. #Security Impact: >When the text size was large enough the service resulting in a momentary outage in our non-production environment (not high-availability). An internal reproduction showed isolated disruption but no outage in our production environment. #Mitigation: >To mitigate, please restrict limit of user input field of Full name like you have already enforced on the fields E-mail and User name. If you need more info, be free to ask. Happy to help. Regards, @smit
