wpasupplicant: Disable D-Bus auto-activation on all calls

Browse source 
Every method call and property access to fi.w1.wpa_supplicant1 used flag
0, leaving D-Bus service activation enabled. Any stray request — a startup
race before `service wpa_supplicant start` takes effect, or a leaked call
while the Ethernet uplink is the chosen path — would make the bus daemon
spawn `wpa_supplicant -u` from its .service file, bypassing repeater's own
launch of the daemon.

Route every interaction through callNoAutoStart/getPropNoAutoStart/
setPropNoAutoStart, which set dbus.FlagNoAutoStart. A leaked call now fails
cleanly with ServiceUnknown instead of resurrecting the daemon, leaving
repeater as the sole launcher.
