Description

We want to retroactively process events for strategies that were previously unhandleable and now we have the corresponding handler implemented. For this we create the RetroactiveProcessor an independent class from the main Orchestrator.
Also, we introduce a new table so we checkpoint every event we process and can safely manage a critical error and restart retroactive processing without processing an event twice.

Checklist before requesting a review

• I have conducted a self-review of my code.
