Phase 13. Two new packages and one new screen. internal/health owns the shared status vocabulary (ok/warn/error/unknown) and the local checks: supervisord's process table, TLS certificate expiry and the two milter sockets. Each check reports a problem as a status rather than an error, so one broken component costs a line and not the page. internal/dnscheck does the read-only lookups: forward-confirmed reverse DNS for SELFPOST_HOSTNAME, and per-domain DKIM (compared against the key this server actually signs with), SPF and DMARC. Every check is bounded by a timeout and cached, and the resolver sits behind an interface so the tests drive every branch without touching the network. The SPF check is deliberately shallow: it looks for a mechanism literally covering the server's address and does not follow include:/redirect=, so a record that authorises us through an include is reported as "cannot tell" rather than as a failure. /status renders both, with the local checks in an HTMX-polled fragment and the DNS lookups behind a Re-check button, and becomes the panel's landing page: / now redirects there and the domain list lives at /domains. The Reload button moves onto /status, where it reads as what it is — a drift-recovery for the daemons — with text explaining what it regenerates. A template test fails on any remaining href="/" so a stale link cannot silently land on the wrong screen. Also fixes a defect this made visible: the panel could never read the mail queue in the documented deployment. postqueue relies on its setgid-postdrop bit, which the compose file's no-new-privileges disables, so the Queue screen always said "Could not read the mail queue" — including in the released 1.0.0 image. The panel user is now a real member of postdrop, which needs no setgid transition. Verified in a container on the dev server against real DNS: PTR matching (selfpost.mixfed.ru) and not matching (mixfed.ru), DKIM absent and mismatched, SPF absent and via include:, DMARC p=quarantine/p=reject/absent, and a resolver timeout degrading to "unknown" without hanging the page.
