Description

Thank you for implementing the prometheus configuration. It is super helpful!

Would it be possible to add the following prometheus env var to follow GitOps best practices:

1. PROMETHEUS_ENABLE: boolean to enable/disable Prometheus endpoint
2. PROMETHEUS_ALLOWED_ROUTES: comma-delimited values of allowed IPs/CIDRs

I'm going to leave this open for reasons, but "this" project is going to move to mostly UI based configuration.

Keep an eye out early 2026 for some GitOps/IaC/AaC goodness.
