Move the portable modular service base from nixos/modules/system/service/portable/ to lib/services/, making it importable by any module system (home-manager, nix-darwin) without reaching into the nixos/ tree. Moved files: service.nix, lib.nix, config-data.nix, config-data-item.nix, test.nix. All external references updated (systemd/system.nix, doc/manual/default.nix, assertions.nix, README.md). No functional changes - only import paths differ.
