[BUG]: `register_public_key_event` is backwards

[sgerbino]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current behavior

address should be the first argument, public_key should be the second argument.

message register_public_key_event {
   bytes public_key = 1 [(btype) = BASE64];
   bytes address = 2 [(btype) = ADDRESS];
}

Expected behavior

message register_public_key_event {
   bytes address = 1 [(btype) = ADDRESS];
   bytes public_key = 2 [(btype) = BASE64];
}
