This pull request updates the environment variables for worker containers and improves the related test coverage. The main changes involve adding a new environment variable to expose the consumer name and modifying the Redis DSN format for workers.

Environment variable improvements:

• Added a new environment variable MESSENGER_CONSUMER_NAME for worker containers, which is dynamically set to the Pod's metadata name using a field reference. [1] [2]

Redis DSN updates:

• Updated the MESSENGER_TRANSPORT_DSN value for workers to remove the /consumer segment from the Redis DSN path, aligning it with the expected format. [1] [2]

Test enhancements:

• Updated tests in store_test.go to check for the presence of the new MESSENGER_CONSUMER_NAME environment variable and to verify the modified Redis DSN format. [1] [2]
