Roll cephrgw-operator to v0.2.0 (radosgw-native) (#273)

## Why

cephrgw-operator **v0.2.0** rebuilds the Ceph integration to talk directly to radosgw via **go-ceph** (Admin Ops API) + **aws-sdk-go-v2** (S3), replacing the manager-dashboard client, and adds **fine-grained bucket-access policies** (paths / actions / conditions / rawStatements). The operator now authenticates with an **RGW admin user's access/secret key** instead of a dashboard login.

Operator repo PRs: unkin/cephrgw-operator #3 (rebuild) and #4 (fine-grained), both merged; tag `v0.2.0`.

## Changes

- bump the operator image `git.unkin.net/unkin/cephrgw-operator` → `v0.2.0`
- update the `envFrom` / `VaultStaticSecret` comments to the `CEPH_RGW_*` credential keys the new image consumes

## Required manual step (runtime)

The VaultStaticSecret copies the KV secret's keys **verbatim**, so the seed must be re-put with the new keys before/with rollout — otherwise the operator fails auth:

```
vault kv put kv/kubernetes/namespace/cephrgw-system/default/cephrgw-credentials \
  CEPH_RGW_ENDPOINT=https://s3.ceph.unkin.net \
  CEPH_RGW_ADMIN_ENDPOINT=https://radosgw.service.consul:443 \
  CEPH_RGW_ACCESS_KEY=<key> CEPH_RGW_SECRET_KEY=<secret>
```

(The old `CEPH_DASHBOARD_*` keys are ignored by v0.2.0.) VSO refreshes within 5m and the `reloader` annotation restarts the operator.
