feat: anchor the launcher top-center and add a wallpaper banner

Matches the launcher position already in use (north-anchored, 600px, single
column) rather than the centered grid, and restores the wallpaper banner behind
the input area from the old darknix theme.

The wallpaper path cannot be committed: rofi does not expand a tilde inside a
url(), and an absolute path would bake in a home directory. So launcher.rasi
carries a placeholder and the installer generates the real file. The entry sits
on a solid plate so it stays legible over a bright wallpaper.
