Wire dms.service to hyprland-session.target -- DMS never actually launched

hyprland.conf's exec-once starts hyprland-session.target, but the installer
never created that systemd user unit or wired dms.service to it, so
Hyprland launched fine while DMS/quickshell (panel, dock, spotlight, all
keybinds routed through it) silently never started. Added
install_session_target(), which writes the unit file (same content already
working on the reference machine) and runs daemon-reload + add-wants.
