feat: Add proper logging of simulation/extend/restore events (#1774)

* feat: Add proper logging of simulation/extend/restore events

* feat: consolidate diagnostic event logging

- Use tracing logs with DEBUG and TRACE for contract events and diagnostic events respectively.
- Use Printer to display the events in a more human readable way.
- Simulate once to determine if an invoke should send and use that result instead of simulating again

* fix: logging test
