Enable DMS dock via IPC -- it defaults off and was never turned on

DMS's dock (showDock/dockAutoHide/dockUseOverlayLayer) defaults to off in
its own settings; nothing in the installer ever enabled it, so the panel
bar could come up fine with no dock visible at all. Added
configure_dms_dock(), which enables it via `dms ipc call settings set` when
DMS is reachable, and prints a clear manual fallback + skips quietly
(doesn't fail the install) if DMS isn't running yet -- e.g. a first-ever
install before the user has logged into Hyprland even once.
