fix: kill NetworkManager's dnsmasq before starting our own

Browse Source 
NetworkManager auto-starts its own dnsmasq when creating a hotspot,
which conflicts with our DNS-hijacking dnsmasq on the same interface.
Now kill ALL dnsmasq instances before starting ours.

fix: set AP hotspot password to fixed WPA2 PSK "12345678"
fix: kill NetworkManager's dnsmasq before starting our own
Open network was not viable as nmcli generates random password by default.
Use a simple fixed password since the AP is only for short-lived provisioning.
