feat: Enable Quarkus management interface at build time

Add application.properties with quarkus.management.enabled=true
as a build-time property. This enables a separate HTTP server
on port 9000 for health/ready/live endpoints, using its own
thread pool independent from the main Vert.x event loop.

Without this, health probes share the same event loop that gets
blocked for 10-20+ seconds during Iceberg commits and GCS uploads,
causing K8s to consider the pod unhealthy and restart it.

+# Management Interface: espone health/ready/live su porta separata (9000)
+# con thread pool indipendente dal Vert.x event loop principale.
+# Motivazione: durante operazioni I/O pesanti (commit Iceberg verso GCS,
+# upload Parquet), il Vert.x event loop si blocca per 10-20+ secondi,
+# causando timeout sulle health probe K8s che usano la stessa porta 8080.
+# Con il management interface su porta 9000, le probe rispondono sempre
+# anche durante i blocchi, evitando restart inutili del pod.
