hailin c05722bbb3 fix(mpc-service): enable shutdown hooks for graceful Kafka disconnect 
Root cause: When mpc-service restarts, the old Kafka consumer doesn't
properly disconnect, causing the broker to wait for sessionTimeout
(~5 minutes) before completing rebalance. This blocks app startup.

Solution: Enable NestJS shutdown hooks with app.enableShutdownHooks().
This ensures onModuleDestroy() is called on SIGTERM/SIGINT, which calls
consumer.disconnect() and allows immediate rebalance on next startup.

Also reverted the "don't await consumer.run()" workaround since the
proper fix is graceful shutdown.
