fix(entry): the two report boxes stop moving as well

Once the callsign stopped giving up its width, the RST boxes were the
next widest things in the row and became the ones that shifted when the
date field appeared. Both are now a notch narrower and shrink-0, like the
callsign; "59+20" is the longest report either ever holds and still fits.
