Get workspace status

What this workspace is, and what it can actually do. The first call a client should make: whether payments and yield are live, simulated or unavailable, the workspace clock, running totals, and a description of its configuration. Secrets are never included.

unavailable means nothing can pay in this workspace now: its Circle credentials are stored but cannot be read; or it is on Arc mainnet with no Circle account connected yet, or not live yet; or this deployment has Arc mainnet switched off. A cycle refuses to pay then rather than fall back to simulation, so status does not report it as simulate. Yield is also unavailable on a network with no yield reserve, such as Arc mainnet.
