📄 Description

Changes
This change builds on #10503, enabling exposing prometheus metrics via an environmental variable rather than updating the system configuration file. This is necessary in containerized environments where the configuration file is not available at startup and requires some workarounds when deploying to Kubernetes. Additionally, users can specify a separate HTTP port to host the /metrics endpoint. If set to 0 - the default - the /metrics endpoint will be exposed on the default server port.

Users can set the following environmental variables to configure metrics at startup:

JELLYFIN_EnableMetrics
JELLYFIN_MetricsListenPort

As requested in the original PR, the changes have been moved to ServerConfigurationManager.

Issues
Fixes #6247
