Fix backups - #342

…ends) (#3403)

## What this PR does

Bumps the etcd-operator to **v0.5.3**, which carries the S3
request-checksum fix
([cozystack/etcd-operator#342](cozystack/etcd-operator#342)).
`git compare v0.5.2...v0.5.3` is exactly #340, #341, #342.

**Why:** scheduled etcd snapshots to non-AWS S3-compatible backends
(**Ceph RGW** confirmed) fail at upload. Since early 2025
`aws-sdk-go-v2` defaults `RequestChecksumCalculation` to
`WhenSupported`, which stamps a CRC32 on every upload; over HTTPS a
multipart part rides it as `x-amz-content-sha256:
STREAMING-UNSIGNED-PAYLOAD-TRAILER`, and RGW rejects it with `400
InvalidArgument`. v0.5.3 sets `WhenRequired` on both the S3 client and
the transfer manager, so multipart uploads (>5 MiB — every real etcd
snapshot) carry no checksum trailer.

**Changes:**
- `system/etcd-operator` — `appVersion` v0.5.2 → v0.5.3 (image tag
follows AppVersion; `values.yaml` keeps `tag: ""`), bump
`ETCD_OPERATOR_REF`, update deployment unittest expectations.
- `system/etcd-operator-crds` — re-vendor CRDs from v0.5.3.
`etcdmembers` gains the additive #340 `status.version` field +
**Running** printer column and picks up the `peerAutoTLS` spec field the
vendored copy was already missing (all additive, backward-compatible;
`etcdclusters`/`etcdsnapshots` unchanged). Fixes the stale `make update`
(upstream has no `config/crd` kustomization — CRDs live in
`charts/etcd-operator/crd-bases`) and makes it fail loudly on a fetch
error (temp file under `set -e`, not a pipe).

**Verification:** `helm unittest` 18/18 and `helm template` green on
both packages; regenerated CRDs are byte-identical to upstream
`crd-bases` at v0.5.3. End-to-end on a live Ceph RGW backend
(freedom-portal-stage): the v0.5.2 (client-only) agent fails a multipart
snapshot upload with the 400; v0.5.3 uploads an 11 MiB multipart
snapshot successfully, and the operator-driven CronJob→EtcdSnapshot path
reaches `Complete`.

### Downstream repositories

Walked the trigger map in `docs/agents/contributing.md` file-by-file
against the diff (`packages/system/etcd-operator{,-crds}/**` only — a
component version bump + additive CRD re-vendor). Nothing matches: not
an `apps/`/`extra/` package add/rename/remove, no `core/platform`
values, no variant/bundle, no platform component add/remove, no `hack/`
layout or shared-tooling change, and the provider does not type the
`etcd-operator.cozystack.io` CRDs (and the change is additive/opaque
regardless).

### Release note

```release-note
fix(etcd-operator): bump to v0.5.3 — etcd snapshot uploads to non-AWS S3-compatible backends (Ceph RGW, some MinIO/R2) no longer fail with `400 InvalidArgument: x-amz-content-sha256 ...`; the snapshot agent now requests a checksum only when required, on both the S3 client and the multipart transfer manager. Also brings observed EtcdMember versions (#340) and `--watch-namespace` (#341).
```
