♻️(frontend) redirect the user agent to the logout endpoint

Recent updates in the backend views now requires the user agent to be
redirected to the logout endpoint.

The logout endpoint should initiate the logout flow with the OIDC provider,
by redirecting the user to the OIDC provider domain.

Thus, OIDC provider session cookie should be cleared.

E2E tests should be improved later on, when the CI and the development env
use Agent Connect integration environment. The current logout is not working
with the Keycloack configuration.
