How to Test:

+
    +
  1. Click "Create 2-min Test Token" to simulate a login session
    2. +
  2. Wait for the warning modal to appear (should show at 5 minutes, but our test token expires in 2 minutes)
    3. +
  3. Click "Create 30-sec Token" to test the warning appearing quickly
    4. +
  4. Test the "Stay Logged In" button to refresh the session
    5. +
  5. Wait for automatic logout when token expires
    6. +
  6. Verify notifications appear for different events
    7. +
