LOG-7889: Fields not getting pruned for loki output

[Clee2691]

Description

This PR decouples Lokistack labels from Loki.

For Lokistack:

• App and infra logs will include log type, host, and container labels along with their Otel equivalents.
• Audit logs will NOT include container labels but will include log type and host labels along with their Otel equivalents.

For Loki:

• log type, host, and container labels will be added by default without their Otel equivalents if no LabelKeys are defined.
