VPN: a WireGuard tunnel (#8)
The device joins a WireGuard network over whatever Wi-Fi it is on: one
peer, IPv4. A client's .conf is imported from the card (/vpn/wg0.conf) and
kept in the device's settings, private key included, never shown; Settings
offers to delete the file. A switch brings the tunnel up until the next
restart, "Start with Wi-Fi" every time; it waits for the clock, which a
handshake needs. VPN shows in the Status Bar.

The protocol is esphome/wireguard 0.4.8. It calls lwIP without lwIP's lock,
which this framework checks: every call into it is made with the lock held.

What goes through the tunnel is everything (AllowedIPs 0.0.0.0/0) or the
one subnet the device's tunnel address is in: lwIP routes by an
interface's subnet or by default, nothing finer. The import says how many
ranges it can't reach.
