boban 6927987a0d harden(fleet,infra): enforce credential revocation on the poller + prod container hardening
From the whole-codebase re-audit (deferred MEDIUM findings, Codex-reviewed):

- poller: CredentialVault enforces a credential's disabled_at lock only at connect(), but
  PollMetrics reuses one long-lived SSH connection per server, so a credential disabled
  mid-run kept streaming metrics over the already-open session. Add Server::withActiveCredential()
  (whereHas credential whereNull disabled_at); the poller selects via it and prunes any cached
  client whose server left the active set, so a revocation drops the server on the next tick and
  closes its session promptly.
- prod compose: add security_opt no-new-privileges:true to every service + a generous pids_limit
  (fork-bomb backstop). cap_drop/read_only are deliberately left out — they need a per-service
  prod smoke test (nginx :80 bind, entrypoint chown) before enabling; documented inline.
- Caddyfile + compose: strengthen the TRUSTED_PROXY_CIDR guidance — an over-broad value in
  external-TLS mode lets any client forge X-Forwarded-For and defeat the IP-keyed throttles + ban.
