fix(menu): case-insensitive filter on all rofi -dmenu menus

dmenu mode is case-sensitive by default (dmenu compat), so config.rasi
case-sensitive=false fixed apps/drun but not nomarchy-menu pickers.
rofi_menu helper always passes -i; networkmanager_dmenu gets rofi -i.

V0: flake check --no-build green. V3: type sys in root Menu → System.
