feature(event-sourcing): baseline for the architecture review fixes.

- fixed the tool overlay in tui.
- fixed tool calling - added schemas.
- getting all sessionIds via event store.
- instead of sending all events on the replay - there's a new way for replaying.
- session snapshot is now a thing getting sent for previously created sessions.
- added logging to important parts.
- revert workflowId from WorkflowCompletedEvent.
