Alexey Artamonov 0335276b61 feat(postgres): render a KEDA ScaledObject for read-replica autoscaling

Implement the KEDA-based read-replica autoscaler for postgres per the
merged design proposal (cozystack/community#44):

- cozy-lib.keda.scaledObject: engine-agnostic helper rendering a KEDA
  ScaledObject (scale target, effective bounds, prometheus trigger,
  scale-down behavior, optional pause), fail-closed on bad input.
- postgres: an `autoscaling` values block (enabled / minReplicas /
  maxReplicas / target / maxReplicationLagSeconds / dryRun). Under active
  autoscaling the chart drops the static .spec.instances so Flux and the
  KEDA-managed HPA no longer contend, and renders a ScaledObject whose
  minReplicaCount folds in the synchronous-quorum floor
  (max(minReplicas, maxSyncReplicas+1, 2)); when the floor exceeds
  maxReplicas, quorum wins. dry-run keeps the static count and pauses the
  ScaledObject. The WorkloadMonitor tracks the quorum floor instead of a
  stale static value.

Covered by helm unittest (cozy-lib helper: valid render, pause, three
fail-closed guards; postgres: instances dropped, quorum-floored bounds,
quorum-over-max, dry-run pause). Regenerated values.schema.json, README,
Go types and postgres-rd.
