The barman-cloud plugin injects its sidecar without resource requests or
limits. Tenant namespaces ship a LimitRange that defaults containers to
128Mi, so the sidecar inherits that default and is OOMKilled mid-backup:
the ObjectStore stays healthy, the Cluster stays Ready, and only the
backup fails. A cgroup high-water mark of 254 MiB on a 38 MB database
shows the default cannot hold it.
The shared cozy-lib helper and the Go path that builds the platform's own
ObjectStore now request 100m/256Mi and cap memory at 1Gi. No CPU limit is
set, matching the entityOperator precedent in the kafka chart: a
throttled sidecar stalls WAL archiving instead of failing it.
The helper is renamed from checksumSidecarConfiguration to
sidecarConfiguration, since it no longer carries only the checksum pin.

Address review on the S3 request-checksum fix:
- Extend the fix to the platform-managed useSystemBucket=true flow, whose
ObjectStore is built in Go by applyClusterPluginBackup (SSA-applied), not
chart-rendered. Add InstanceSidecarConfiguration to cnpgtypes.ObjectStoreSpec
and set AWS_REQUEST_CHECKSUM_CALCULATION=when_required on it via
barmanSidecarConfiguration(). The platform's own default system bucket is
SeaweedFS, a non-AWS S3 gateway of the same class as Ceph RGW. Unit test in
cnpgstrategy_controller_test.go asserts the applied ObjectStore carries it.
- Factor the duplicated instanceSidecarConfiguration block (3x across two
charts) into a shared cozy-lib helper (cozy-lib.barman.checksumSidecarConfiguration).
