feat: add Everclear relayer app context (#4912)

### Description

Tracks messages from the hub/spoke contracts here
https://docs.everclear.org/resources/contracts/mainnet (HubGateway
(Everclear hub) <> EverclearSpoke (all other spoke chains)). Went with
sender tracking to help us flag if there are other new spokes that pop
up
