Token Storage and State Mismatch

[0marSalah]

Summary:

• Inconsistent token key usage between Redux and localStorage:
  • src/redux/slices/auth.ts → getLocalStorage('auth')
  • src/tools/auth.ts → ACCESS_TOKEN_KEY = 'auth'
  • src/App.tsx → getLocalStorage('auth')
• If Redux update fails after token exchange (e.g., Google login), user appears logged-in locally but Redux state disagrees.
• No error handling if localStorage write fails.

Impact:
Leads to ghost sessions and UI desync.

Suggested Fix:
Centralize token handling (single key constant + wrapper utility) and synchronize Redux + localStorage updates transactionally.
