The checks engine, the path and the cards: me-web? 0.1 reads the connection

MeWeb.Core runs seven checks concurrently and reports each as it settles:
online or behind a login page, this connection, the public IPv4 and IPv6
seen from v4./v6.meweb, the provider from a built-in map, the router
(UPnP IGD, NAT-PMP and PCP, read-only), address sharing (router WAN
against the echo, TTL hops only as a hint), and the history kept on the
device. The app draws the path from this device to the internet and lights
it node by node, with a card per check and a sheet listing every host it
contacts.

The provider map is iptoasn's table compressed to 2.1 MB by
tools/knowledge.cs and built before every app release; eleven Italian
provider profiles carry each fact with who said it, the source and the
month. The server gains a download page (en, it) and /download/{platform}
from the latest Gitea release.
