theme: calm YoRHa lock screen and power menu; nvim and btop follow

The lock screen and the power menu lose the last Persona motion: no split
display type, no grid sweeping in behind a dark column, no tilted slabs, no
skewed password blocks or hard shake. Both are now one small group of type in
the dark — the porthole mark, a line of light display type, a status line, and
either a rounded password field that fills with dots or a NieR menu whose
selected row is a pill of light (rust for the session-ending three). The lock
keeps the wallpaper almost whole; a wrong password nudges the field once and
turns it to rust. P5Backdrop and the grid texture had no users left and go.

Neovim moves to a local yorha colorscheme (nvim submodule) and btop gets a
yorha theme with hairline boxes and grey-to-light gradients.
