[feat](trx-frontend-http): make the APRS list a log, and read the payloads

A frame was a card five lines tall — timestamp, a meta line, the
information field as it arrived on the air, three buttons, and a Details
panel repeating the four things already on the row — so five frames
filled the panel and the payload was left to be decoded by eye.

A frame is one line now: time, station, type, and what the frame says.
It opens in place for the path, the CRC, the raw field, its bytes and
the actions.  Twenty-one frames fit where five did.

And the information field is read rather than echoed.  Weather reports
give temperature, wind, humidity and pressure; telemetry gives its
sequence and channels; a message gives its addressee and text; a
position gives the fix, course and speed, and the comment the station
wrote.  Anything that cannot be summarised falls back to the raw field,
which is in the expanded view either way.

HF APRS had a copy of the same forty lines of markup, differing by one
badge, so both now build their rows from one function in the shared
module — the CSS is shared between them and this would have broken it
otherwise.  Both headers lose their three summary cards for a line of
counts beside the filters, which frees another fifth of the panel.
