- 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.

Covers the POP3 TRANSACTION state machine via scripted sessions over
net.Pipe, mirroring the SMTP handler test harness: STAT/LIST/UIDL/DELE/
RETR/TOP/NOOP/RSET/QUIT including argument error paths, deleted-message
behavior, dot-stuffing, RETR/TOP source error paths, mailbox load
errors, session read error handling (idle timeout vs other), and the
TCP listener lifecycle (Start/serve/Notify/Drain).
No production code changes; current behavior is pinned as-is. Two
known RFC deviations are documented in tests (RETR/TOP of messages
marked deleted) for follow-up fixes. Package coverage: 24.4% -> 93.2%.

This change makes all header timestamps (e.g. "Received") to use
UTC time zone.
This way the length of such headers do not depend on local time zone
which if effect fixes#404.
