Remove unused Kubernetes and Docker configuration files

The commit removes obsolete Kubernetes and Docker configuration files like indexer.dockerfile, various YAML files for Kubernetes resources, and PostgreSQL configurations. These files are no longer relevant to the current project setup.

- Deleted `indexer.dockerfile`, previously used for Docker image creation, as it is no longer required.
- Removed Kubernetes deployment files like `configmap.yaml`, `db-secrets.yaml`, `indexer-deployment.yaml`, and more, as the project no longer operates in a Kubernetes environment.
- Deleted PostgreSQL Helm values file (postgresql-values.yaml) and related setup scripts, which are no longer being referenced.
