Jean-Pierre MartineauandClaude Opus 5 972c0b6f03 Screens: Esc is the way out, so no row spends two lines saying so
The app-wide Back row existed because it duplicated Esc — two of its call
sites said as much in a comment. On both platforms Esc is a labelled key
and every footer hint names it, so the row bought nothing for the blank
separator and line it took out of every screen; on the PicoCalc's 26 rows
that is a row in thirteen.

back_rows() is gone, and with it the four hand-drawn copies: ReorderScreen's
clean-state row, the live feed's pinned foot stop (the cursor now clamps on
the oldest packet), node detail's tail action, and the action-list rows on
the trace and TX-sweep screens.

Kept, because there leaving is a choice rather than an exit — the same rule
that keeps a dialog's Cancel button: exit_rows()' staged pair, where Apply
has no key of its own and ✗ Back names what the other way out costs;
ReorderScreen's dirty-state pair; the two Quit rows, which initiate the
app's terminal action behind a confirm; and the new-record dialog's Close,
which is its default, so dropping it would let a reflex Enter navigate.

With no Back row there is no Back value: the six spellings callers used to
test three at a time (_BACK, "__back__", _CANCEL, two tuple shapes, bare
None) collapse to `is CANCEL` / `is None`. The gallery now asserts the
absence of an exit row on every screen, on both platforms.

Resolves findings E and §10 of docs/survey-navigation.md. Finding D — Esc
peeling a filter on three screens and leaving on two — still stands, and is
now the only thing left telling a user what Esc does.
