The tab read the followed list, the horizon and the locator once, when it
was mounted. It is normally open BEHIND the settings window while those
are edited, so un-following QO-100 left it in the pass table and in the
dropdown until the tab was reopened — indistinguishable, from the
outside, from a setting that had not saved at all.
SaveSatSettings now emits sat:settings, and the panel reloads the birds
and the passes on it, the same way it already does on sat:tle. One event
for every key: they all change what the tab should be showing. The
selection needs nothing new — a satellite that has stopped being
followed drops out of the dropdown, and the effect that keeps the
selection inside that list moves to the first one remaining.
