Many resources created as part of managed apps in cozystack (pods,
secrets, etc) do not carry predictable labels that unambiguously
indicate which app originally triggered their creation. Some resources
are managed by controllers and other custom resources and this
indirection can lead to loss of information. Other controllers sometimes
simply do not allow setting labels on controlled resources and the
latter do not inherit labels from the owner. This patch implements a
webhook that sidesteps this problem with a universal solution. On
creation of a pod/secret/PVC etc it walks through the owner references
until a HelmRelease is found that can be matched with a managed app
dynamically registered in the Cozystack API server. The pod is mutated
with labels identifying the managed app.
```release-note
[cozystack-controller] Add a mutating webhook to identify the Cozystack
managed app that ultimately owns low-level resources created in the
cluster and label these resources with a reference to said app.

## Summary by CodeRabbit
* **New Features**
* Added support for a new "Client" topology mode in SeaweedFS, enabling
integration with remote filer endpoints.
* Introduced new configuration options: `filer.external` to allow
external filer access, and `remoteEndpoint` for specifying a remote
filer service when using "Client" topology.
* Added new Kubernetes resources (Deployment, ServiceAccount,
ClusterRole, ClusterRoleBinding, BucketClass, BucketAccessClass) for
object storage provisioner in "Client" mode.
* Added a LoadBalancer service for external filer access when enabled.
* **Improvements**
* Enhanced configuration schema and documentation to reflect new
topology and parameters.
* Updated role and access control for dashboard resources.
* Improved detection and validation of deployment topology, preventing
unsupported changes post-deployment.
* **Bug Fixes**
* Ensured VerticalPodAutoscaler resources are not created when using
"Client" topology.

This change is aimed at improving the development experience.
- The option `make delete` has been added.
- Added check for `NAME` and `NAMESPACE` variables
- Now, any package (not just system ones) can include options such as
make show, make diff, make apply.
- Applications from packages/extra require explicit specification of the
`NAMESPACE`.
- Applications from packages/apps require explicit specification of both
`NAME` and `NAMESPACE`.
