EnableLogin localStorage session expiration

[tomroth04]

🐞 Describe the bug
The web app stores the session token in localStorage, which Safari automatically clears after 7 days of inactivity. This causes users to be logged out unexpectedly, requiring frequent re-authentication.

💻 Components impacted
Web app

💡 Screenshots and/or logs
Not applicable.

🔮 Additional context
Using cookies (with appropriate expiration) instead of localStorage for session tokens (especially when the EnableLogin option is active) would prevent automatic session expiry issues in Safari.
