Dev - #2

Here’s a more natural student-style PR description:

What we changed

In this PR we finished and cleaned up our project before submission.

We fixed the main app routing through NGINX, updated the monitoring setup, added host/container metrics, improved logging, and added a smoke test script to check that the whole stack works correctly.

We also added a GitHub Actions workflow, updated Docker Compose configs, and rewrote the README in a shorter and simpler student style.

Main updates

• fixed access to the app through 127.0.0.1
• checked load balancing and rate limiting in NGINX
• added node-exporter and cadvisor
• updated Prometheus and Grafana config
• added an infrastructure dashboard
• checked Loki/Promtail logging
• added scripts/smoke_test.sh
• added GitHub Actions CI/CD workflow
• simplified README
• removed unnecessary extra monitoring README

What we tested

We tested the project locally by:

• starting the whole stack with Docker Compose
• checking app endpoints
• checking Prometheus targets
• opening Grafana dashboards
• checking logs in Loki
• running the load tester
• running the smoke test script

Result

Now the project is in a much cleaner and more complete state, and we can use it for the final report and demo.
