Refactor Dockerfile for scraper, update Traefik configuration, and clean up scripts

- Simplified Dockerfile for scraper by removing unnecessary Node.js installation and optimizing build stages.
- Updated Traefik environment configuration to use shorter variable names for certificate paths.
- Removed commented-out middleware configurations in dynamic middlewares.yaml.
- Cleaned up legacy SSL configurations in ssl.yaml.
- Disabled insecure API access in Traefik configuration.
- Deleted unused renovate.json file.
- Modified update environment script to only process apps directory.
- Updated GHCR cleanup script to target specific package.
- Streamlined dependency update script to focus on app submodules.
- Removed setup script for Prometheus as it is no longer needed.
