The XF86 binds survived the noctalia -> eww switch, but the popup they
drew did not, so volume and brightness changed with no feedback. swayosd
replaces it: swayosd-client both applies the change and draws the OSD.
Also fixes two binds that pointed at binaries no host installs any more:
XF86AudioMicMute called volumectl (avizo, removed) and the brightness
keys called brightnessctl, which only arrakis has.
Commands are referenced by store path because Hyprland execs binds with
the PATH the session was started with.
