feat(hub): Phase 8 — Hub v2 security hardening + production readiness

8.1  Config-based admin authz (require_admin on all admin endpoints)
8.2  Email encrypted at rest (AES-256-GCM, HKDF from hub Ed25519 key)
8.3  Refresh token rotation with family-based reuse detection
8.4  Federation persistence (HubPeer model replaces in-memory dict)
8.5  Federation token verification now async (DB-backed)
8.6  CSAM hash check wired into swarm registration flow
8.7  Rate limiting on auth endpoints (5/10/20 per minute)
8.8  Healthcheck endpoint (GET /v1/health, no auth)
8.9  IP log cleanup background task (365-day retention)
8.10 Argon2id params bumped to 256 MB (pw_version, rehash on login)

Deployed to meshbay.org — schema migrated, existing emails encrypted.
117 tests pass (29 hub, 88 common+node).

Resolves security review items S1, S2, S5.
