feat(eventindexer): Event indexer

[cyberhorsey]

New backend service to index for various events without any processing or handling.

Exposes an API as well.

Currently this is used to capture BlockProven events, and return them via an API for the status page and for informational purposes.

i dont think the lint/build can pass until this is merged into main though.
