Livstick Client API V2.1

API 2.1 is the V2 surface Livstick keeps running in production, not a deprecated one: it sits on the same key management as v3 — hashed secrets, expiry, status, audit and scope enforcement — and only its shapes are inherited. Each operation below has its own page, generated from the specification the service publishes, so it stays exact as the surface evolves. Two things the specification cannot tell you on its own: the base URL is not published here, it is provided with your access; and details is a POST even though it only reads, a habit carried over from the original V2 design.
