Instrument Docker Compose setups to enable Application Observability

[ppcano]

• Fixed the Tempo configuration so tracing works as expected locally.
• Fixed the local Prometheus Data Source configuration to enable Drilldown app for Quickpizza metrics.
• Made service.instance.id and service.namespace configurable for trace data.
• Added service_name and service_namespace labels to metrics and logs in Docker Compose.
• Enabled the host metric needed for Application Observability.

These changes should be safe for existing Kubernetes deployments — nothing should break there.

I'll open a new issue to discuss potential instrumentation enhancements.

Haven't run this locally but the changes look good to me.

We might want to look into using the faro receiver for the local setup to also have something resembling frontend-o11y in the local variant
