feat: bring the power menu confirmation dialog into the theme

The yes/no gate in front of shutdown was still on the old adi1090x theme, so
every shutdown showed a Macchiato power menu followed by a dialog that did not
match it.

Its glyphs now come from the theme's own Nerd Font rather than `feather`. That
meant changing the codepoints the script sends, since the originals were
Private Use Area points that only feather carries: they are now the Material
circled check and close (U+F05E0, U+F0159), which Inconsolata Nerd Font Mono
contains. Sized 42 to match the power menu, since the Material glyphs carry a
lot of internal padding and render small.

Worth knowing for future glyph choices: ClearlyU is installed and claims large
parts of the Private Use Area, so it can win fontconfig's fallback and draw a
blank where another font actually has the glyph. The U+F0xxx Nerd Font ranges
avoid that.
