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.

```release-note
[cozystack-api] Fix: Sanitize v2 schema
```

## Summary by CodeRabbit
- Bug Fixes
- Improved OpenAPI/Swagger v2 compatibility by normalizing schemas
(handle int-or-string patterns, remove unsupported oneOf/anyOf, and fix
empty additionalProperties), producing more consistent v2-compliant
definitions.
- Refactor
- Added internal v2 post-processing to sanitize schemas across all
definitions without changing public APIs.
- Tests
- Added end-to-end OpenAPI tests validating v2, v3 and protobuf v2
endpoints and integrated them into the test suite.
- CI
- Added an OpenAPI test step to the pull-request workflow so OpenAPI
tests run during CI.
