[service-utils] fix: crash if Kafka connects more than once

[arcoraven]

PR-Codex overview

This PR introduces a mechanism in the KafkaProducer class to ensure that the connect() method is called only once using a promise. This change improves connection management by allowing concurrent calls without redundancy.

Detailed summary

• Removed the isConnected boolean flag.
• Added a connectPromise property to manage the connection state.
• Modified the connect() method to cache the connection promise.
• Updated the message sending logic to always call await this.connect().
