cleanup: Shift wpad reload from handler to instead occur in-place

We cannot afford to defer things to a handler when reconfiguring the
network: we need to know as soon as possible when our playbook has
gone up in flames and left a remote out-of-reach, so we can know what
broke when we have to go and directly service the unit.

I've hard-set the timeout here to 70 to handle the full one-minute DFS
CAC timeout, but please, for the love of God, don't run mesh on
UNII-2A. You do not want to be waiting that full minute for the device
to come back.
