a2c8f906 added checkpoint_timeout=15min + max/min_wal_size to the CNPG
Cluster YAML, but the cluster is applied via null_resource.pg_cluster +
local-exec kubectl apply, which only re-runs when its `triggers` change.
The YAML edit didn't bump a trigger, so the change was inert and never
applied (incl. via CI). Bump the pg_params trigger so the kubectl apply
re-runs and CNPG hot-reloads the new params (reloadable, no restart).
Landing it via a targeted apply (-target=null_resource.pg_cluster) to avoid
3 pre-existing unrelated drifts in this stack -- notably a mysql_standalone
volumeClaimTemplate annotation diff the apiserver rejects as immutable,
which is what fails broad dbaas applies (and silently blocked a2c8f906).
