fix(authentication): create a new cache partition on open login web-view

[ShGKme]

☑️ Resolves

Step to reproduce:

1. Start the login process
2. Log in as User1
   
3. Before finishing the process, realize that you actually wanted to log in as User2
   
4. Close the login WebView
5. Open again
   • Expected: You can log in as User2
     
   • Actual: You are still logged in as User1 and can only grant access to Talk Desktop
     

Note: non-persist stores partition until app restart, not window reopening.

🚧 Tasks

• Create a new cache and storage partition on each Login WebView open, so previous cookies + session are not reused
