Shared chat link context lost after authentication

[Wolftousen]

Bug Description

When following a shared chat link (e.g., https://prism.liatr.io/chat/shared/cf5cd0ca-ba1b-4d11-b2a7-6a9afaa6b060) while not authenticated, the system loses the original shared chat context after authentication completes. Users must manually re-enter the shared chat URL to access the intended conversation.

Steps to Reproduce

1. Receive a shared chat link (e.g., https://prism.liatr.io/chat/shared/cf5cd0ca-ba1b-4d11-b2a7-6a9afaa6b060)
2. Click the link while not authenticated
3. Complete the authentication process
4. Observe that you are not redirected to the original shared chat
5. Must manually paste the original shared chat URL to access the conversation

Expected Behavior

After authentication completes, the system should automatically redirect the user to the originally requested shared chat URL.

Current Behavior

The system loses the original shared chat URL during the authentication flow, requiring manual re-entry of the URL to access the shared chat.

Impact

• Disrupts the user experience when trying to access shared conversations
• Creates unnecessary friction in the collaboration workflow
• May lead to confusion or lost context for users

Additional Notes

• This specifically affects the handling of shared chat URLs
• The system should maintain the original URL as the intended destination through the auth flow
