Logs out the current user.

Terminates the current user session by invalidating the authentication token. This action logs the user out of the application but does not automatically log the user out of the OIDC provider. If accessed via a browser, this endpoint will initiate the OIDC logout flow, if configured, to log the user out of the OIDC provider as well. After completing the OIDC logout flow, the user is redirected back to the application login page.
