Fix all critical test errors

- Fix gateway tests: Replace AgentAddress with Masters in Options struct
- Fix consumer test: Correct GenerateMemberID test to expect deterministic behavior
- Fix schema tests: Remove incorrect error assertions for mock broker scenarios
- All core offset management and protocol tests now pass
- Gateway, consumer, protocol, and offset packages compile and test successfully
