Refactor NixOS module and flake configuration for lidarr-mb-gap

- Updated `flake.nix` to streamline output definitions and improve readability.
- Refactored NixOS module configurations in `nixos/lidarr-mb-gap.nix` for better structure and clarity.
- Simplified the package import process in `nix/package.nix` by removing unnecessary parameters.
- Enhanced example configurations in `nixos/EXAMPLE_CONFIG.nix` to align with the new structure.
