Refactor Nix configurations to update URLs from hypervirtual.world to rougebordeaux.xyz

- Updated flake.nix to change Alejandra and other inputs to follow the new repository structure.
- Modified uptime-kuma configurations to reflect the new domain for Caddy reverse proxy settings.
- Adjusted various multimedia services in Sisyphe to use the new domain for Caddy virtual hosts.
- Disabled the Sabnzbd service in Sisyphe and updated its Caddy configuration.
- Corrected multiple service configurations in Sisyphe to point to the new domain, including Grafana, Nextcloud, and Synapse Matrix.
- Ensured all references to hypervirtual.world are replaced with rougebordeaux.xyz across all relevant files.
