AWS LoadBalancer-specific settings were not applied even when custom annotations were needed.

After applying the Helm chart change

# kagent/templates/ui-service.yml

apiVersion: v1
kind: Service
metadata:
  name: {{ include "kagent.fullname" . }}-ui
  namespace: {{ include "kagent.namespace" . }}
  labels:
    {{- include "kagent.ui.labels" . | nindent 4 }}
  {{- with .Values.ui.service.annotations }} ############# add
  annotations: ############## add

  {{- end }} ############## add
spec:

      protocol: TCP
      name: ui
  selector:
    {{- include "kagent.ui.selectorLabels" . | nindent 4 }}

my custom kagent values.yaml

ui:
  service:
    type: LoadBalancer
    annotations:
      #### https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.13/guide/service/annotations/
      service.beta.kubernetes.io/aws-load-balancer-name: kagent-dashboard
      service.beta.kubernetes.io/aws-load-balancer-type: external
      service.beta.kubernetes.io/aws-load-balancer-scheme: "internet-facing"
      service.beta.kubernetes.io/aws-load-balancer-nlb-target-type: "ip"
      service.beta.kubernetes.io/aws-load-balancer-cross-zone-load-balancing-enabled: 'true'

Added support for service.annotations in the Helm chart.
AWS LoadBalancer annotations can now be configured through Helm values.
The generated Service resource correctly includes AWS LoadBalancer annotations.

Changes:
