* Closes #3464. Sets the supply to 1M ACME by default to prevent negative supply issues.
* Refactors the snapshot indexer to allow mmap to be disabled due to [a bug in rr](https://github.com/rr-debugger/rr/issues/3635).
* Panics if batch commit fails, since that is a fatal error and if returned it can be masked.
