Audiobuzz 9c86cd4c5a fleet-manager: checkpoint 4 — InfluxDB metrics gateway (write + Flux read) 
The manager is the ONLY thing that talks to InfluxDB, both directions; hosts hold
no token and never reach it.

- influx.go: influxSink implements MetricsSink — each agent HealthSnapshot is
  written as a fleet_health point, identity (serial/hostnqn/starship) as TAGS
  from the AUTHENTICATED stream (a host can only write its own series), telemetry
  as fields. QueryField answers the SPA's read: a Flux query built with a strict
  FIELD WHITELIST + hex-serial guard + parsed-duration range, so no caller input
  is interpolated raw (injection-safe). Server-side influxdb-client-go/v2.
- admin.go: GET /api/hosts/{serial}/metrics?field=&range= -> time-series JSON;
  503 when InfluxDB isn't wired, 400 on a bad range, 404 for unknown host.
- main.go: sink created when FLEET_MGR_INFLUX_URL+_TOKEN set, fed to the agent
  hub; nil -> no-op sink so the manager runs without metrics.

Tests: snapshotPoint tags/fields/time, fluxQuery contents + %q quoting, and
QueryField rejects a non-hex serial + non-whitelisted field. build/test/vet/gofmt
clean. Live InfluxDB path validated in the compose bench (ckpt 6).
