Add extraManifests support to charts

[pkill2913]

Summary

Adds extraManifests support across the Helm charts, allowing users to render additional Kubernetes objects from the same Helm release.

This is useful for creating supporting resources required by the chart deployment, such as pre-created Secrets, ConfigMaps, RBAC objects, or other Kubernetes manifests, without requiring a separate Helm chart or an additional deployment
step.

The manifests are rendered through Helm templating via tpl, similar to the KEDA extra manifests pattern.

Y deja el testing igual:

Testing

• Rendered extraManifests with a templated ConfigMap name using {{ .Release.Name }}
• Ran helm lint for all charts
• Ran helm lint with extraManifests enabled for falcon-sensor, falcon-kac, falcon-image-analyzer, and falcon-platform
