feat: update log process ordering

[frisitano]

Overview

This PR implements 2 changes:

• Ensures that notifications are sent in the same order as their corresponding log was emitted on L1
• Changes the logic of batch reverts such that we do not update the fcs when we are still actively syncing from L1.

TODO

In a follow-up issue, we should clean up some unnecessary code in the watcher related to the old log parsing pattern.
