Fix eon column in tx pointer table

Here, the eon refers to the keyper config index, not the keyper-internal
eon. Note that the tx pointer is also read by other parties including
validators, so using the proper eon (from Shuttermint) which is only
meaningful in a keyper DKG context does not make sense.

We should rename the message field in the spec at some point.
