ui: the sidebar is two tabs, and a toggle disables its pane

Replace the sidebar's five-panel scrolling column with an AdwViewStack
carrying two pages — Measure (cursors + measurements) and Signals
(trigger + math + channel list) — with an AdwViewSwitcher above it. The
trigger and cursors toggles change from "reveal/hide my pane" to
"enable/disable my feature, leaving the pane insensitive", following the
disable-not-hide principle. The keys probe loses a duplicate registration
that was toggling the sidebar back on before the exit probe captured its
state; the exit-probe captures now read adw_overlay_split_view_get_show_
sidebar() instead of gtk_widget_get_visible(), which AdwOverlaySplitView
never changes.

The order is the file's, and it is the one thing here that is not self-evident: `pack_end()` lays its
children out right to left, so a `<child type="end">` is added leftwards-from-the-right in document order
and the screen reads the reverse of it — cursors, measurements, math, sidebar, menu.

What is *not* here is as deliberate as what is. Everything this file nests is fixed — the shape of
the window does not depend on the stream, the trigger or the layout — while the subtrees that do are
