feat: CLI modules for all 25+ service clients

One cli.rs per SDK module, gated behind #[cfg(feature = "cli")]:
- auth (identity + hydra): identity, session, recovery, schema,
  courier, health, client, jwk, issuer, token, SSO passthrough
- vcs (gitea): repo, issue, pr, branch, org, user, file, notification
- chat (matrix): room, message, state, profile, device, user, sync
- search (opensearch): doc, query, count, index, cluster, node,
  ingest pipeline, snapshot
- storage (s3): bucket, object
- media (livekit): room, participant, egress, token
- mon (prometheus, loki, grafana): queries, dashboards, datasources,
  folders, annotations, alerts, org
- vault (openbao): status, init, unseal, kv, policy, auth, secrets
- la suite (people, docs, meet, drive, mail, cal, find)

All dispatch functions take (cmd, &SunbeamClient, OutputFormat).
