[medium] Split worker-service queue consumers by domain

[davedumto]

Summary

worker-service currently runs all queue consumers as one undifferentiated pool, making it hard to scale or monitor by domain.

Requirements

• Split consumers into domain-specific groups such as transactions and verification
• Allow each group to scale independently
• Add tests verifying each consumer group only processes its own queue
• Document the new consumer topology in worker-service README
