Update images, fix some minor issues and improve qol

[pizkaz]

Updates

• updates elasticsearch
• updates alpine base for parsedmarc

Fixes

• runs parsedmarc in offline mode because DNS lookups are failing
• includes mounted folders, so folder permissions are initialized when cloning the repository (avoids permission denied errors)

Quality of life improvements

• renames parsedmarc config for out-of-the-box operation
• mounts parsedmarc config so the OCI image must be built only once
• installs required Grafana plugins in OCI image
• waits for elasticsearch readiness before starting parsedmarc
