Update dependencies in requirements.txt to latest versions

Catch SigningError separately (logged at ERROR level) and fix the ack/nack
logic so failed messages are requeued once then discarded, instead of being
requeued indefinitely or lost. Remove the bare `raise e` that crashed the
worker after each error.
