cli: migrate the CLI and integration tests to the v1 HTTP API

Replace the gRPC client with the generated HTTP client across every
command: locally over the unix socket without auth (matching the previous
local gRPC socket), remotely over TLS with a Bearer API key. Output
rendering and integration tests move to the HTTP client types; the
transport changes, the assertions do not.
