This commit resolves an issue with the global exchange name and updates the database connection client name. The `.env.example`, `CHANGELOG.md`, and `src/api/integrations/rabbitmq/libs/amqp.server.ts` files were modified. The exchange name in the AMQP server and global queues initialization has been changed to use the value from the configuration service. Additionally, the database connection client name has been updated in the `.env.example` file. The change in the `CHANGELOG.md` file has been updated accordingly.
