Pierre-Olivier Mercier e4b6481d32 checker: split monolithic rule into per-concern rules
Replace the single matrix_federation rule with individual rules for
federation status, well-known delegation, SRV records, connection
reachability, TLS checks, and homeserver version, so the UI surfaces a
clear checklist. Drop the incorrect well-known/server_name equality
check: m.server points at the delegated federation endpoint, which is
intentionally distinct from server_name.
