Write a drop's app data — replace the shared-memory state (the JSON key/value object mirroring the app's localStorage), so you can update what the app holds (mark a task done, add a row…). Read it first with read_data, modify the object, write it back WHOLE. Only works on a drop with server memory (an account drop) — an anonymous drop's data lives in the browser and can't be written here. expectedVersion (from read_data) is REQUIRED: the write is rejected (version_conflict) if the data changed meanwhile — re-read and retry, so you never overwrite blindly. For a fresh state, read_data returns version 0. With an account token, owned drops need no managementToken.
