## What this PR does
This patch fixes an issue with the Cozystack API server that causes it
to respond with the first registered dynamic list kind when listing
dynamic resources. E.g., when running `k get postgreses`, the raw JSON
response from the cozystack API would be
```json
{
"apiVersion":"apps.cozystack.io/v1alpha1",
"kind":"BootBoxList",
"items": [
{
"apiVersion":"apps.cozystack.io/v1alpha1",
"kind":"Postgres",
...
},
...
],
...
}
```
The root cause is the way the `Typer` interface is implemented for the
`runtime.Scheme` where the dynamic types are registered. Since the base
type for all dynamic types is a `&cozyv1alpha1.Application{}`, all types
are registered under the same key and the `Typer` defaults to the first
`GroupVersionKind` that was registered. Only when a correctly formed
`&unstructured.Unstructured{}` is returned by the API, is this resolving
logic circumvented and the `GroupVersionKind` is instead inferred from
the fields of the returned object. Even an `UnstructuredList` is not
acceptable as a return type, instead the `items` key should be directly
set on the underlying `map[string]interface{}`.
This patch implements the changes detailed above. Additionally, the
following features, fixes, and improvements are added:
* Makefile targets to build and run the Cozystack API locally, against a
Kubernetes server in the environment's KUBECONFIG. Debugging with Delve
is also supported.
* CI tests are added to verify the new changes.
* A bug in the registration of the corev1alpha1 types is fixed.
* Updated the `ConvertToTable` function to properly handle list kinds
which might be of the `&unstructured.Unstructured{}` concrete type (not
an `UnstructuredList`).
* The scheme used by the API server's Client and WatchClient is
separated from the scheme used to serve dynamic types.
* The client config for reading the runtime configuration now uses the
controller-runtime, which handles flags and environment variables
properly, unlike `clientcmd`.
### Release note
```release-note
[api] Fix incorrect list kind for list requests to the Cozystack API for
dynamic resources. Add Makefile targets for local testing. Minor schema
building improvements.
```

## Summary by CodeRabbit
* **Tests**
* Added an end-to-end test validating Kubernetes API kinds for tenants
and ingresses.
* **Chores**
* Improved local development: ignore local API server config, added
run/debug targets with local TLS tooling, and added an OpenSSL config
for CSR generation.
* **Refactor**
* Internal API server and registry storage reworked; may affect
integrations expecting concrete resource types.
