[wlfrdoconc]

Depends on #115. Please review this PR after #115 is merged.

Summary

Adds Grafana dashboards to visualize SCE TV download bitrate metrics. This includes an instantaneous bitrate graph for each download along with rolling average bitrate graphs over 30 seconds, 5 minutes, and 30 minutes.

How to Run

Start the development environment:

docker compose -f docker-compose.dev.yml up --build

Open the following in your browser:

• SCE TV: http://localhost:5001
• Prometheus: http://localhost:9090
• Grafana: http://localhost:3000

In Grafana, open the SCE TV Download Metrics dashboard.
