Feat: implement signature publisher decorators in signer

[dlachaume]

Content

This PR includes the implementation of signature publisher decorators in the signer node, introducing a retrier publisher and a delayer publisher to facilitate future integration with a DMQ-based diffusion mechanism.

Additionally, signature publisher parameters have been made configurable to support execution in both end-to-end test and production environments. The default values are:
SIGNATURE_PUBLISHER_RETRY_ATTEMPTS: 3 attempts
SIGNATURE_PUBLISHER_RETRY_DELAY_MS: 2,000 milliseconds
SIGNATURE_PUBLISHER_DELAY_MS: 10,000 milliseconds
