style(details): size the Info tab fields to their contents

Six equal columns gave a US county name the same width as a two-digit CQ
zone: the county truncated while the zones, the prefix and the DXCC
number sat mostly empty. The row is twelve columns now, spans set per
field.

The bearing and the two distances are read-only and never exceed
"12345 km", so they move to a flex row at a fixed width and the address —
the one field here that was never wide enough — takes the remainder.
