fix: Add localStorage and sessionStorage to ESLint globals

[platzhersh]

Summary

Updated ESLint configuration to recognize localStorage and sessionStorage as global objects, preventing "undefined variable" linting errors when these Web Storage APIs are used in the codebase.

Changes

• Added localStorage and sessionStorage as readonly globals in the browser environment configuration
• Added the same globals to the browser test environment configuration to ensure consistency across all browser-based linting contexts

Details

These Web Storage APIs are standard browser globals and should be recognized by ESLint to avoid false positive linting errors. By marking them as readonly, we prevent accidental reassignment while allowing their normal usage throughout the application.

localStorage now in sight!
No more lints shall cry in pain,
When storage globals are plain,
The rabbit hops with pure delight! ✨
