feat(rofi): wallpaper banner and placeholder on the ssh header

The header and search bar share the wallpaper banner the Alt+F2 runner
uses, each on a plate so it stays legible over any image, and the entry
gets a placeholder. ssh.rasi now carries the @WPAPER@ placeholder, so
install.sh generates it like launcher.rasi instead of linking it.
