James Hillyerd 8bad098be9 refactor(pop3): extract transaction handler helpers (#619) ...

- validateMsgNum parses and range-checks message-number arguments,
  replacing five copies of the parse/check/respond sequence in the
  LIST, UIDL, DELE, RETR and TOP arms (wire responses unchanged).
- listMessages implements LIST and UIDL, which differ only in the
  per-message value reported.
- sendMessageLines unifies sendMessage/sendMessageTop via a body line
  limit, negative meaning unlimited.

Adds a direct unit test for validateMsgNum and an equivalence test
asserting TOP with a large line limit matches RETR output. All
scripted session tests from the previous commit pass unchanged.
