[feat](trx-frontend-http): give the AIS list the same log shape

A message was three stacked lines — time and name, then MMSI and route,
then motion, distance, position and age — so a screen held eight of
them.  It is one line now: time, vessel, message type, and what the
message says, opening in place for the MMSI, the channel frequency, the
route, the age, the fix and a jump to the map.  Twenty-two fit where
eight did.

What a message says depends on what it is.  Position reports give the
fix and the motion; the static and voyage reports that carry no fix give
the callsign and where the vessel is bound.  Both fall back to whatever
fields are present rather than showing nothing.

The row vocabulary the APRS list introduced is no longer APRS-specific —
the classes are decode-line and decode-expanded now, shared by both, and
identity sits in fixed columns so the summaries line up down the list
instead of starting wherever the callsign happens to end.  The three
summary cards above the list go the way of the APRS ones.
