FreeDVReporter: only force column relayout on visibility/highlight changes

setColumnAutosize_() forces a full column relayout (SetWidth() on every
column) on macOS, worked around a wxWidgets rendering bug (see
https://github.com/wxWidgets/wxWidgets/issues/25972). It was firing
whenever any row's data changed at all (isPendingUpdate), not just when
a row's visibility or highlight color changed. On a busy reporter
network, isPendingUpdate can be true on effectively every 250ms
highlight-timer tick, so this was running continuously rather than only
when column widths could plausibly need to change -- matching an
observed symptom of the Reporter window's headers redrawing themselves
very frequently.

Plain data refreshes still go through ItemsChanged() so cell content
stays live; only the column-width relayout is now skipped for them.
