## What this PR does On the default `cozy-default` / `useSystemBucket` backup flow, the ClickHouse chart pointed the `clickhouse-backup` sidecar's `S3_ENDPOINT` straight at the projected `cozy-backups-creds.endpoint`, which the backup credentials projector stores as a **bare host** (no scheme) by design. `altinity/clickhouse-backup` runs `S3_ENDPOINT` through the aws-sdk-go-v2 endpoint resolver, which rejects a scheme-less value with `Custom endpoint 's3.host' was not a valid URI` — so every ClickHouse backup and restore on the default flow failed. Reproduced live on a v1.6.2 cluster: a `cozy-default` `BackupJob` against a `useSystemBucket: true` ClickHouse hangs, and the sidecar logs `S3 ResolveEndpoint ... was not a valid URI`. The fix prepends `https://` on the `useSystemBucket` path via a helper env plus `$(VAR)` expansion (a `secretKeyRef` value can't be string-interpolated), mirroring the platform's `backupstrategy-controller.endpoint` helper which force-prepends `https://` for the always-TLS external S3 ingress. The legacy and bring-your-own-Secret paths keep reading `endpoint` verbatim, since that value is tenant-supplied and already carries its own scheme. ClickHouse was the only `cozy-default` app hit by this. I audited every default-flow app: the CNPG/postgres, etcd and velero strategies already get a scheme'd URL from the endpoint helper, and mariadb and foundationdb deliberately pair a bare host with a separate TLS flag; mongodb reads a full URL from its own chart values. So this is the single scheme-class fix needed. Not addressed here (separate, non-scheme gaps surfaced during the audit, flagged for follow-up): MongoDB has no `useSystemBucket` wiring at all (its `cozy-default` strategy assumes a manually-configured `backup.endpointURL` + per-app S3 creds), and FoundationDB's self-signed-CA trust to the operator pod is a known gap. ### Screenshots Not applicable (no UI changes). ### Downstream repositories No schema or API change (only a chart template and its helm-unittest). `values.yaml` / `values.schema.json` / the CRD are untouched, so nothing downstream is affected.
