Some random tune-ups for aqi

Some random tune-ups for aqi

 * BIG fix for openthread routing on FTDs - we just weren't configuring
   all the required parameters and so it would work fine as a child, but
   never promote.  To keep that from being hardcoded we're now using the
   menuconfig defines under "Openthread" platform data or whatever
 * Remove esp32-wifi-manager for now, it had its own mDNS implementation
   and I just didn't want to deal (will prob add it back later)
 * PWM features around tuning, both frequency and target parsed from
   JSON, auto-selects the widest duty resolution too
 * A messy recheck GPIO feature for motion detection. It doesn't really
   work and I need to figure a better way to drain spurious activations
 * Disabled CONFIG_PM_ENABLE temporarily but we can bring it back I'm
   sure
