jellyseerr: add user modification methods

addded permissions get/set before realizing it already comes as part of
the User object. Split User attributes that will be templated into
UserTemplate struct, which User inherits. ApplyTemplateToUser takes a
UserTemplate, while ModifyUser takes a plain map with some typed fields
(display name and email, for now).
