The per-packet trace goes behind RP412CAMLOG

Playback is confirmed good - Cyd on the replay: "it looks as good as the
Live cam view" - so the scaffolding that got it there can come down.

DispatchPacket's line per packet earned its keep: one of them identified
the spool's own header being parsed as packet one, which was the whole
crash. But a station in a pod bay has no business writing two dozen log
lines at the start of every replay, and the pods are where this is headed.
Gated on RP412CAMLOG, kept rather than deleted, because the next thing to
go wrong in this path will want it back.
