theme: YoRHa dark — NieR:Automata interface on the space-1 wallpaper

Replaces the Persona x Mocha rice. NieR's menu language is kept whole —
plain rectangles, hairline rules, letter-spaced upright capitals, a square
marker on the current row, corner ticks round panels, and selection shown
by inverting the row — but the colours come from ~/.wallpapers/space-1.jpg
rather than from the game's beige: the grey-green void as the ground, the
suit's sage grey as text, the planet's white as the one accent, and the
hull's red indicator lights as the alarm.

The Persona geometry is switched off rather than ripped out: Theme.skew
and Theme.cut are 0, so P5Panel, Skew and Geom collapse to rectangles.
Overshoot easing, italics and black weights are gone shell-wide.

New, borrowed from caelestia's screen border: bar/Frame.qml draws the bar,
the rail and a thin left/bottom band as one hull on the bottom layer, with
the desktop as a rounded opening cut out of it. Frame also owns all four
exclusive zones, so the bar and rail are placed from the screen edge.

Hyprland moves to 1px borders lit from the planet white into grey, a soft
wide shadow and gaps measured from the opening. Alacritty, fish and dunst
get matching YoRHa palettes. Neovim, GTK/Qt and btop are still Mocha.
