Describe the bug

After a fresh install of Keycloak 26.0.2, on first login with a temp-admin user, the UI displays a "Forbidden, permission needed: query-clients" even if the user has admin role.

Version

Regression

[X] The issue is a regression

Expected behavior

The administrator (or temp-admin) can see the list of Clients in the master Realm.

Actual behavior

When the administrator tries to list the Clients for the master Realm, a puzzling "Forbidden, permission needed: query-clients" appears briefly, then the Clients are shown.

How to Reproduce?

create and run Dockerfile
```
FROM quay.io/keycloak/keycloak:26.0.2

ENTRYPOINT ["/opt/keycloak/bin/kc.sh","start-dev", "--bootstrap-admin-username", "temp-admin", "--bootstrap-admin-password", "Myp4ssword!!!"]
```
with a valid Postgres 16 db.
On first login with temp-admin credentials, you'll see the problem (reproduces every time).

Anything else?

I tried starting a discussion before filing this bug.
