feat(install): reload running apps after generating configs

install.sh wrote every config and reloaded nothing, so a scheme switch looked
half-applied: the files were correct but waybar, kitty, conky and dunst kept
drawing the old colours until five commands were run by hand.

It now signals waybar, kitty and Hyprland, runs udt-accent (which regenerates
the accent and restarts dunst), and restarts conky, which has no hot-reload.
Each is guarded on the process actually running, so a missing one is skipped
rather than started: verified conky stays stopped when it was not up before.

rofi needs nothing, it reads its theme per launch. Qt and GTK apps still need
a manual restart and the README says so.
