[ingress] Enforce HTTPS-only for API

This patch updates the default API Ingress to add the
nginx.ingress.kubernetes.io/force-ssl-redirect annotation,
ensuring all HTTP traffic (port 80) is redirected to HTTPS (port 443).
This prevents unencrypted external access and improves security.

```release-note
[ingress] Force HTTPS access for api.dev3.infra.aenix.org and block direct HTTP.
```
