SSR-Safe localStorage Usage

[lak7]

Problem: In src/app/settings/settingsClient.tsx direct localStorage usage without SSR safety checks can cause hydration mismatches in Next.js server-side rendering contexts.

Context: This line is executed in handleGithubOAuthDisconnect function within a client component, but without checking if window is defined or using proper SSR-safe patterns.

Expected Behavior: localStorage operations should only occur on the client side after hydration is complete, typically wrapped in useEffect or with typeof window !== 'undefined' checks.
