Describe the bug

Hello,

sine the new feature to log authenticated user has been done here, it seems that when you logout, username is not displayed in log.

Here an example with logout from oauth2:

1.2.3.4 - - [11/Sep/2026:06:37:07 +0000] "GET /oauth2/logout?next=/browser/ HTTP/1.1" 302 6269 "https://pgadmin4.youpi.fr/browser/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/152.0.0.0 Safari/537.36"

Here an example with "classical" logout:

1.2.3.4 - - [11/Sep/2026:06:34:21 +0000] "GET /logout?next=/browser/ HTTP/1.1" 302 205 "https://pgadmin4.youpi.fr/browser/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/152.0.0.0 Safari/537.36"

To Reproduce
Deploy pgadmin4 and enable LOG_AUTHENTICATED_USER, click on Logout button.

Expected behavior

Add missing username in log:

1.2.3.4 - me@youpi.fr [11/Sep/2026:06:34:21 +0000] "GET /logout?next=/browser/ HTTP/1.1" 302 205 "https://pgadmin4.youpi.fr/browser/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/152.0.0.0 Safari/537.36"

Desktop (please complete the following information):

• OS: Kubernetes 1.34.8
• pgAdmin version: 9.17
• Mode: Server
• Browser (if running in server mode): Chrome/152.0.0.0
• Package type: Container

Hello,

yes and the fix is working :)

The issue is "only" on the GET /logout (or GET /oauth2/logout if you use oauth2 authent)

WITHOUT this fix, you don't have username:

1.2.3.4 - - [13/Sep/2026:17:54:17 +0000] "GET /oauth2/logout?next=/browser/ HTTP/1.1" 302 6269 "https://pgadmin4.youpi.fr/browser/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/152.0.0.0 Safari/537.36"

And WITH the fix, you have the username:

1.2.3.4 - me@youpi.fr [13/Sep/2026:17:50:09 +0000] "GET /oauth2/logout?next=/browser/ HTTP/1.1" 302 6269 "https://youpi.fr/browser/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/152.0.0.0 Safari/537.36"
