jellyseerr: use in profiles, apply on user creation and modification

added in the same way as ombi profiles. Most code is copy-pasted and
adjusted from ombi (especially on web), so maybe this can be merged in
the future. Also, profile names are url-escaped like announcement
template names were not too long ago. API client has "LogRequestBodies"
option which just dumps the request body when enabled (useful for
recreating reqs in the jellyseerr swagger UI). User.Name() helper
returns a name from all three possible values in the struct.
