[fix](trx-frontend-http): fix APRS bar coords visibility, cap at 5 entries

Coordinates were clipped by white-space:nowrap on the frame row.
Split each frame into a .aprs-bar-frame-main line (nowrap+ellipsis)
and a separate .aprs-bar-frame-pos line for the coordinate button,
so coordinates are always visible regardless of info length.
Restore 5-entry cap (slice from history).
