BorEventResponse was pulling double duty by being used for block number lookups as well as event lookups.
As a result, we were using EventsByBlock instead of EventLookup and interpreting the presence of the bor TX hash in kv.BorTxLookup by the absence of returned events.
This PR refactors the code so that remote calls to EventLookup use BlockReader.EventLookup, preventing any discrepancies between the two.
