Upgrade barman-cloud library to v0.5.1 which includes lz4 support for
base backups. Update CRD schema and manifest to expose lz4 as a valid
compression option, and clarify docs that lz4 is no longer WAL-only.

When an ObjectStore's credentials change (e.g., secret rename), the
RBAC Role granting the Cluster's ServiceAccount access to those
secrets was not updated because nothing triggered a Cluster
reconciliation.
Implement the ObjectStore controller's Reconcile to detect affected
Roles and update their rules directly, without needing access to
Cluster objects. The controller lists Roles by a label set by the
Pre hook, inspects their rules to find which ObjectStores they
reference, fetches those ObjectStores, and patches the rules to
match the current specs.
Replace the custom setOwnerReference helper with
controllerutil.SetControllerReference. Add dynamic CNPG scheme
registration (internal/scheme) to the operator, instance, and
restore managers.

The restore manager used a hardcoded scheme registration that ignored
CUSTOM_CNPG_GROUP and CUSTOM_CNPG_VERSION, causing restore jobs to fail
under non-standard CNPG API groups.
Extract `generateScheme()` into `common.GenerateScheme()` and use it
from both instance and restore managers.

The e2e kustomize overlay tried to match
`docker.io/library/plugin-barman-cloud` but the base kustomization at
`kubernetes/kustomization.yaml` already transforms the bare
`plugin-barman-cloud` image to the GHCR name. The overlay must match
the base's output (`ghcr.io/cloudnative-pg/plugin-barman-cloud-testing`)
to override it.
Broken since b7daaac (#89) changed the base kustomization's newName
from `docker.io/library/plugin-barman-cloud` to the GHCR image without
updating the e2e overlay.

Replace hardcoded Go version across the Taskfile and Dockerfiles with a
single `GO_VERSION` variable extracted from go.mod's `toolchain`
directive. This makes go.mod the single source of truth for the Go
version, removing the need to keep 3 Taskfile tasks and 2 Dockerfiles in
sync via Renovate's custom regex manager.

The operator was not announcing the TYPE_INSTANCE_SIDECAR_INJECTION
capability so the CNPG operator did not consider the plugin enabled
for instance pods. The instance manager never queried the plugin's
metrics endpoint, and the barman_cloud_cloudnative_pg_io_* metrics
were missing entirely.
This bug was masked when isWALArchiver was set to true in the plugin
configuration, because the backward compatibility code in CNPG would
mark the plugin as enabled as a side-effect. Users with isWALArchiver
set to false (or omitted) never saw the new metrics.

### GitHub Vulnerability Alerts
####
[CVE-2026-33186](https://redirect.github.com/grpc/grpc-go/security/advisories/GHSA-p77j-4mvh-x3m3)
### Impact
_What kind of vulnerability is it? Who is impacted?_
It is an **Authorization Bypass** resulting from **Improper Input
Validation** of the HTTP/2 `:path` pseudo-header.
The gRPC-Go server was too lenient in its routing logic, accepting
requests where the `:path` omitted the mandatory leading slash (e.g.,
`Service/Method` instead of `/Service/Method`). While the server
successfully routed these requests to the correct handler, authorization
interceptors (including the official `grpc/authz` package) evaluated the
raw, non-canonical path string. Consequently, "deny" rules defined using
canonical paths (starting with `/`) failed to match the incoming
request, allowing it to bypass the policy if a fallback "allow" rule was
present.
**Who is impacted?**
This affects gRPC-Go servers that meet both of the following criteria:
1. They use path-based authorization interceptors, such as the official
RBAC implementation in `google.golang.org/grpc/authz` or custom
interceptors relying on `info.FullMethod` or `grpc.Method(ctx)`.
2. Their security policy contains specific "deny" rules for canonical
paths but allows other requests by default (a fallback "allow" rule).
The vulnerability is exploitable by an attacker who can send raw HTTP/2
frames with malformed `:path` headers directly to the gRPC server.
### Patches
_Has the problem been patched? What versions should users upgrade to?_
Yes, the issue has been patched. The fix ensures that any request with a
`:path` that does not start with a leading slash is immediately rejected
with a `codes.Unimplemented` error, preventing it from reaching
authorization interceptors or handlers with a non-canonical path string.
Users should upgrade to the following versions (or newer):
* **v1.79.3**
* The latest **master** branch.
It is recommended that all users employing path-based authorization
(especially `grpc/authz`) upgrade as soon as the patch is available in a
tagged release.
### Workarounds
_Is there a way for users to fix or remediate the vulnerability without
upgrading?_
While upgrading is the most secure and recommended path, users can
mitigate the vulnerability using one of the following methods:
#### 1. Use a Validating Interceptor (Recommended Mitigation)
Add an "outermost" interceptor to your server that validates the path
before any other authorization logic runs:
```go
func pathValidationInterceptor(ctx context.Context, req any, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (any, error) {
if info.FullMethod == "" || info.FullMethod[0] != '/' {
return nil, status.Errorf(codes.Unimplemented, "malformed method name")
}
return handler(ctx, req)
}
// Ensure this is the FIRST interceptor in your chain
s := grpc.NewServer(
grpc.ChainUnaryInterceptor(pathValidationInterceptor, authzInterceptor),
)
```
#### 2. Infrastructure-Level Normalization
If your gRPC server is behind a reverse proxy or load balancer (such as
Envoy, NGINX, or an L7 Cloud Load Balancer), ensure it is configured to
enforce strict HTTP/2 compliance for pseudo-headers and reject or
normalize requests where the `:path` header does not start with a
leading slash.
#### 3. Policy Hardening
Switch to a "default deny" posture in your authorization policies
(explicitly listing all allowed paths and denying everything else) to
reduce the risk of bypasses via malformed inputs.

### Security
- server: fix an authorization bypass where malformed :path headers
(missing the leading slash) could bypass path-based restricted "deny"
rules in interceptors like `grpc/authz`. Any request with a
non-canonical path is now immediately rejected with an `Unimplemented`
error.

Update github.com/cloudnative-pg/barman-cloud from the pre-release pin
(ced266c) to the official v0.5.0 release.
This update fixes a race condition in parallel WAL restore where
prefetched files could be read while still being downloaded, causing
PostgreSQL recovery to fail with "invalid checkpoint record" errors. It
also fixes a misleading "missing Azure credentials" error message when
no object store credentials are defined at all.
