Describe the bug
By default, Applications -> Outposts -> Authentik Embedded Outpost -> Advanced Settings -> Configuration -> kubernetes_ingress_class_name is set to null. Changing this to any other value has no effect on the actual kubernetes ingress class.

To Reproduce
Steps to reproduce the behavior:

1. Run 'kubectl get ingress ak-outpost-authentik-embedded-outpost' and note the CLASS (it's null by default).
2. Navigate to Applications -> Outposts -> Authentik Embedded Outpost -> Advanced Settings -> Configuration -> kubernetes_ingress_class_name - set this to 'nginx' and select 'Update'
3. Run 'kubectl get ingress ak-outpost-authentik-embedded-outpost'. CLASS is still null.

Expected behavior
The embedded outpost should reflect the configured kubernetes ingress class name.

Version and Deployment (please complete the following information):
2025.2.4

• authentik version: 2024.4.0 (and earlier)
• Deployment: helm w/ kubernetes nginx ingress

Additional context
Issue has been observed consistently across multiple Authentik instances. Rollout/restart of the server/worker deployments has no effect. If an ingress class is explicitly set by proxied applications, the net result is a 404 error due to the ingress class mismatch.
