feat: add templateId parameter to management user create (#773)

Management user.create was missing the templateId parameter that
invite/inviteBatch already expose. Backend CreateUserRequest accepts
templateId (field 29); wire it through both the options-object and
positional overloads.

Closes descope/etc#17215
