Description
Bring app/etcd/api.lua iproto CALL surface to functional parity with the gRPC surface in app/etcd/pb/defs.lua. 32 already-implemented endpoints need Lua verification tests; 16 missing endpoints (Cluster, Maintenance, Election) need both implementation wrappers and tests. Out of scope: Watch and LeaseKeepAlive bidi-streams, Maintenance.Snapshot/Downgrade. For UNIMPLEMENTED-by-design endpoints, wrappers are created anyway and propagate the same UNIMPLEMENTED error so the surface is uniform.
Acceptance criteria
Every gRPC method in defs.lua (excluding streaming divergences) has a matching etcd_* iproto wrapper. Every wrapper has a Lua testkit test in test/iproto_parity_test.lua asserting response shape and error mapping match gRPC. test/run.lua group iproto/parity passes.
