NonShittyWrapper._setTimer accepts upstream datetime state and piker's
integer packet-nanosecond state. Expiry clears its handle and timeout
before notifying listeners, without replacing packet timestamps.
Tests cover traffic rescheduling, exactly-once expiry, pretraffic and
sentinel handling, disabling, and callback rearming.

Verification: 19 passed, including existing IB history/proxy tests.
Wall-clock packet silence remains distinct from session health.
