Message: MsgVoteOnObservedInboundTx

The MsgVoteOnObservedInboundTx handler is responsible for keeping track of whether an inbound transaction is legitimate by holding a ballot that the observers can vote on. If two thirds of the observers vote in the same way, then the ballot is considered finalized and a new CCTX is generated.

Only valid observers for the sender chain are able to successfully vote on inbound transactions.
