ax(node): enforce TestFilename_Function_{Good,Bad,Ugly} naming in peer_test.go

All peer registry test functions lacked the mandatory category suffix
required by AX-10 (CLI tests as artifact validation / test naming
convention). Renamed every test to carry _Good, _Bad, or _Ugly and
split the former monolithic AddPeer test into three focused cases.
