Group the long pages by what you are trying to do

Notifications repeated both lock-screen switch labels for every application, so
twenty apps meant sixty rows of the same two sentences and the page could not be
scanned at all. Each app is one row now, carrying what its switches add up to --
"On, lock screen shows the sender only", "On, hidden on the lock screen",
"Notifications off" -- with the switches behind it, one app open at a time. The
identifier only appears while an app is open, which is the only time it
disambiguates anything, and the content switch dims when the app cannot reach
the lock screen at all, because there it means nothing.

Shortcuts were already grouped; the problem was that "Windows" caught focus,
movement, splitting, resizing and window state alike and held 43 of the 93
binds. A section that long is a list, not a grouping. They are separated by
intent now -- Focus, Move & split, Size, Window state -- and the split was
checked against the binds this machine actually has rather than trusted from the
keywords. Order matters in two places worth naming: "Next window splits down" is
about splitting rather than focus, and "Focus session" is quiet mode bound to a
workspace rather than window focus, so both are settled before the general
checks.

Refresh rate gets its own row. That need was created by collapsing the
resolution list: the rates for a resolution were only ever reachable by opening
it, so changing nothing but the rate meant going through the mode you already
had. It appears only when the current resolution offers more than one.

Default-application rows carry a chevron, having previously opened a chooser
while looking completely inert.

The notification contract asserted the literal Notifs.appRule(app.id).enabled,
which moved when the rows collapsed. The rule is still read through a binding on
Notifs.appRule, so a rule changed elsewhere still reaches the row -- the
assertion now requires that, rather than requiring one particular spelling of
it.

The power profile rows were left alone. A three-way choice in three rows looks
wasteful until you notice each row explains what the profile does, and that page
has empty space to spare; a segmented control would trade information for space
that is not scarce.
