sway: inhibit screensaver during video playback in mpv and browser

Start xdg-desktop-portal-wlr and xdg-desktop-portal-gtk explicitly so
Firefox can route ScreenSaver.Inhibit DBus calls through the portal chain
to the Wayland idle inhibitor. Add stop-screensaver=yes to mpv.conf for
native Wayland idle inhibition during mpv playback.
