Fix: Add quarkus.oidc.authentication.redirect-path=/auth/callback for OAuth callback handling

Quarkus OIDC needs explicit redirect-path configuration to handle the OAuth callback
from Keycloak at /auth/callback. Without this, the endpoint returns 404 Not Found
causing 502 Bad Gateway during authentication flow.

This fixes the OAuth callback 502 error after successful Keycloak authentication.
