feat(sat): a wider frequency list, a resizable readout, one locator

Three things reported together from the tab.

The shipped frequency plan went from eleven satellites to twenty-five:
the eight Tevel FM cubesats, EO-88, AO-109, CAS-4A and 4B, TO-108,
GreenCube's single-frequency digipeater, and QO-100's wideband
transponder beside its narrowband one. It remains a starting point in a
file the operator can correct — a transponder gets switched and no
release should be needed to follow it — and the picker still lists every
bird in the element set when the "with a plan" filter is unticked.

The readout column drags to any width between 240 and 720 pixels,
double-clicks back to its default, and folds away entirely. How much map
against how much detail is the operator's call: watching a footprint
cross an ocean and working a pass want opposite things.

And the locator is no longer asked for twice. Passes are predicted from
the station locator, which is set once in Station information; the field
here was only ever for an antenna at another site, so it says so and sits
folded away. Nobody should have to wonder which of two locators is in
use.

Also: "Driven by" is two columns wide. "OpsLog (EasyComm II)" did not fit
in a third of the row, and a truncated choice is a choice that cannot be
read.
