less pollution

- Server sends v26_2 login_success with SessionId for protocol >= 776

- Client adds v26_2 login_success handler and scopes v1_21_8 handler to <= 26.1

- Fix WithOtherAccount guard in login server

- Add smart-convert assumption tests for login server/client

- Improve translatePacketVersion error messages
