## What this PR does
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
```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**
- Adds an admission webhook that injects application lineage labels on
resource create/update for improved observability and ownership tracing.
- Adds a runtime-updatable mapping for resolving HelmRelease →
application, and registers both the lineage controller and webhook
during startup.
- Adds Deployment, Service, and cert-manager templates to enable and
secure the webhook (in-cluster TLS, service routing).
- **Tests**
- Adds a test to exercise lineage traversal and validate ownership-graph
resolution and labeling.
