feat(studio): reflect account-voice / series-scope field split

Robot-author edit form and detail drop positioning/target_readers (now
series-level); persona + styles stay (routed to the account profile via the
admin API). Series detail shows positioning/target_readers. Types updated;
admin API types regenerated.
