refactor: Arch changes to address performance bottlenecks

[mattp-swirldslabs]

Changes:

• Block item persistence is now a subscriber to the LiveStreamMediator to make it async
• Now a single response is sent for the entire block rather than for each block item
• Added an additional RingBuffer on the Notifier to handle publishing responses to many producers
• Centralized ringbuffer subscription handling in base class
• Adjusted the previous exception handling to trigger events in the Notifier
• Added configuration and dagger injection mechanisms for new components
• Improvements to subscription handling
• Added metrics for the new response flow and for errors
• Added and adjusted test coverage

Closes #168

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)

Looks good to me, some questions, other than that is fine IMO.

Good Job, leaved some comments, mostly nits some questions and probably future considerations that can be addressed in a future PR.
