🐛 Bug Description

Hi Kagent community and thank you very much for maintaining the project.
During helm installation, we noticed the following issues with helm:

1. Some components do not respect global registry value, as we are using AWS ECR pull through cache with ghcr.io, we tried to set the following but did not work:

querydoc.image.registry
kmcp.image.repository
kagent-tools.image.repository

2. grafana-mcp does not support specifying the image repo name, for the same reason to use ECR pull through cache for docker. setting grafana-mcp.image.registry did not work
3. disabling default agents did not work, as we do not use cilium, we tried setting the following, but the agents are deployed:

agents.cilium-policy-agent.enabled: false
agents.cilium-manager-agent.enabled: false
agents.cilium-debug-agent.enabled: false

The command used is:

helm upgrade --install kagent oci://ghcr.io/kagent-dev/kagent/helm/kagent \
    --namespace kagent \
    --set providers.default=openAI \
    --set providers.openAI.apiKey=$OPENAI_API_KEY \
    --set providers.gemini.apiKey=$GEMINI_API_KEY \
    -f values.yaml

🔄 Steps To Reproduce

Install with the following values:

helm upgrade --install kagent oci://ghcr.io/kagent-dev/kagent/helm/kagent \
    --namespace kagent \
    -f values.yaml

registry: "<random_account_id>.dkr.ecr.us-east-1.amazonaws.com/ghcr"
grafana-mcp.image.registry: "<random_account_id>.dkr.ecr.us-east-1.amazonaws.com/docker/mcp"
querydoc.image.registry: "<random_account_id>.dkr.ecr.us-east-1.amazonaws.com/ghcr"
kmcp.image.repository: "<random_account_id>.dkr.ecr.us-east-1.amazonaws.com/ghcr/kagent-dev/kmcp/controller"
kagent-tools.image.repository: "<random_account_id>.dkr.ecr.us-east-1.amazonaws.com/ghcr/kagent-dev/kagent/tools"
agents.cilium-policy-agent.enabled: false
agents.cilium-manager-agent.enabled: false
agents.cilium-debug-agent.enabled: false

🤔 Expected Behavior

• Global registry should work for all images unless overridden per component
• Being able to disable some of the default agents
