Transitioning from nginx ingress to emissary ingress ✅

I've successfully created all the necessary infrastructure changes to transition from nginx ingress to emissary ingress!

Summary of Changes

Created Emissary Ingress deployment (clusters/kubenuc/apps/emissary-ingress/):

✅ HelmRelease with emissary-ingress chart from datawire repository
✅ 3 replicas with pod anti-affinity for high availability
✅ Resource requests matching nginx config (500m CPU, 512Mi memory)
✅ LoadBalancer service with proper port mappings:
- HTTP (80 → 8080) and HTTPS (443 → 8443)
- UDP port 3478 for Unifi STUN
- TCP port 50000 for Jenkins agent
✅ Prometheus metrics scraping annotations
✅ Listener resources for HTTP and HTTPS traffic
✅ Module configuration for IP forwarding and timeouts (equivalent to nginx settings)

Removed Nginx Ingress:

✅ Deleted clusters/kubenuc/apps/nginx-ingress/ directory
✅ Removed nginx ingress HelmRepository from all clusters
✅ Updated all kustomization files

Updated Chart Repositories:

✅ Added datawire HelmRepository to root and kubenuc cluster charts
✅ Removed ingress-nginx references from all kustomization files

Next Steps

After merging this PR and Emissary is deployed, you'll need to migrate your applications. I found 13 application manifests that currently use nginx ingress:

These apps reference ingressClassName: nginx and nginx-specific annotations. You have two migration options:

Option 1: Keep using Kubernetes Ingress resources

Change ingressClassName: nginx to ingressClassName: emissary-ingress in each app
Update nginx annotations to Emissary equivalents (or remove them if not needed)

Option 2: Use Emissary native resources

Convert Ingress resources to Emissary Mapping and Host CRDs for better control

Applications to migrate:

Portainer, Harbor, SSO/Zitadel, Nextcloud, Jenkins, JFrog ACR
Longhorn, Jellyfin, Mediaserver, S3, Unifi, Cloudflare

Would you like me to help migrate these applications in a follow-up task?
