refactor: simplify Nix module inputs and update configurations

Simplified input argument structures across multiple Nix modules by removing unnecessary bindings and standardizing formats. Enabled `system.primaryUser` setting and updated PAM configuration for sudo touch ID authentication. Removed deprecated or unused configurations, including user fields in metacfg and outdated options in some modules.
