refactor(style): align template literals and whitespace formatting

- standardize string literals to single quotes in constants.js
- remove unused variable and normalize whitespace in cookie.js
- simplify nullish coalescing expression in device-auths.js

This consistency improvement enhances code readability and enforces uniform style across the codebase.
