Title: Refactor deployment to component-based architecture and update CI

Description

This PR refactors the application structure to decouple specific components from the base installation, following the architectural pattern used in the activity-system. By moving these elements into a separate Flux Kustomization, we allow for more modular environment-specific configurations.

Changes

Infrastructure (Kustomize)

Related to:

• feat: Implement Prometheus metrics & switch to Grafana LGTM stack #5 (comment)

• Base Cleanup: Removed the specific component from the base installation to keep the core deployment lean.
• Component Isolation: Created a separate kustomization under components/, mirroring the pattern found in:
  • activity-system/components/observability
• Overlay Update: Updated the staging overlay to include the new component via the components field, as seen in the reference:
  • activity-system/overlays/staging/kustomization.yaml#L12

CI/CD Pipeline

• Workflow Update: Updated the GitHub Action to use the latest version of datum-cloud/actions/.github/workflows/publish-docker.yaml.
• Auto-Deploy: Configured the workflow to automatically trigger deployments to the datum-cloud/infra repository whenever a new release is published, ensuring the environment stays in sync with the latest image.
