fix: restore message widget, fullscreen power menu, and emoji grid

Three regressions from collapsing five theme systems into three layouts.

The layouts hardcoded `children`, which silently dropped any -mesg a script
passed. rofipass lost its keybinding cheatsheet and the power menu lost its
uptime line. list.rasi now lists the message widget; rofi hides it when there
is no message, so it costs nothing when unused.

The power menu was never a small menu. It is a deliberate fullscreen prompt
with a greeting, an avatar and one row of four large glyphs, and menu.rasi
flattened all of it. It gets its own layout, the one place where a prompt earns
its keep. The glyphs are drawn in Inconsolata Nerd Font Mono, which was
verified to contain all four; the old theme asked for `feather`, which contains
none of them and was relying on fallback.

The emoji picker is a dense grid of glyphs, not a list, and wasted most of a
single-column window. It gets grid.rasi, sized near the launcher's icons.
