style(desktop): reformat nix code and simplify module logic

Refactor `modules/desktop/options.nix` to improve code readability through
consistent indentation and whitespace management. Simplified the
conditional logic for `home-manager.extraSpecialArgs` to remove
unnecessary complexity.

Clean up host configurations by removing commented-out code, removing
unnecessary whitespace, and flattening nested attribute sets into
single-line declarations where appropriate.
