fix: repoint worker EXTERNAL_BASE_URL at stable jupiter DNS name

Workers hardcoded jupiter's ClusterIP (10.43.224.63 / 10.43.229.168),
which had gone stale and pointed at nothing. Every request forwarded
from worker-orders, worker-deliveries, worker-customers,
worker-rider-logs, worker-products, and worker-notifications to
jupiter was timing out silently, breaking order creation, delivery
logs, and rider online status. Repointed at the stable in-cluster DNS
name (jupiter.nearle) instead of a ClusterIP so this can't go stale
again after a future service recreation.

Also bumps jupiter to v2.7.57 (Redis client timeout/pool fix) to
match what's already deployed live.
