Subject: [PATCH] Enable Rails built-in health check endpoint at /up

Mounts Rails::HealthController#show at /up (rails_health_check). Returns
200 when the app boots cleanly, 500 otherwise. The controller responds
with an HTML page for browsers/uptime bots and a JSON body for
Accept: application/json clients, so load balancers, monitors, and JSON
consumers share one endpoint. No custom controller.
