We can make use of FluxCD drift detection by setting it to warn, so it emit K8S events on detected drifts.

Pull Request Overview

This PR enables FluxCD drift detection in "warn" mode for all Helm releases, allowing the system to emit Kubernetes events when resources drift from their desired state without automatically correcting them. This provides visibility into configuration drift while maintaining manual control over corrections.

Key Changes:

• Set driftDetection.mode: warn as the default for all Helm release configurations in values.yaml
• Created a reusable Helm template helper for drift detection configuration
• Updated all HelmRelease templates to use the new drift detection helper
