## Objective

Add meaningful tests for the four new series, asserting real behavior and failure modes.

## Steps

1. Test autoscale-target present/omitted based on config.
2. Test disk usage returns for Postgres/KV, omitted for web services.
3. Test active-connections returns real data for a live Postgres instance.
4. Test replication-lag is omitted (not a fake zero) for every instance today.

## Acceptance criteria

- [ ] Tests cover both the present and omitted branches for each series.
- [ ] Tests assert real behavior, not just "returns 200".
