ios: label mini-app threads by their app name, not "Notes" (#198)
Mini-app threads (To-do, Reminders, Poll, …) are kind=="self" threads with the app id encrypted in name_blob — the same kind as the user's own "Notes", which the server can't tell apart. The native thread list returned "Notes" for every self-thread; it now decrypts name_blob and, when an app is named, shows that app's title (from the blob when present, else a small built-in map, else a prettified id). web: createAppThread now also stores the app's display title in name_blob, so a future app is labelled correctly on native clients with no native change.
