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.

Phase 12 (UI/UX). The navigation bar now renders once from layout.html
instead of being copied into each content template, so it is present on
every authenticated page — including the domain page and its delete
confirmation, which had no links at all — and the current page is
highlighted via .Active rather than quietly dropping out of the list.
New /account page changes the administrator's username and/or password:
the current password is required and the attempt is throttled on the same
limiter as the login form, so this route cannot be used to brute-force
past that limit. A password change invalidates every other session while
keeping the one performing it; a rename carries that session over.
Backup and domain import move from a card in the middle of the domain
list to their own /backup page, one card each; the handlers themselves
are unchanged, only the page the import form renders its errors on.
The domain page gains a "Sending server settings" card (server, port,
encryption) so a client can be configured without reading the docs; 587
is listed only when SUBMISSION_ENABLE is true for this deployment, which
is a deploy-time flag the panel cannot verify at runtime.
Client-side (static/panel.js, no libraries): Copy buttons on the values
that get carried elsewhere (DKIM record, new application credentials,
server name), and the Addresses field is hidden while the address mode is
wildcard, where the server ignores it.
Verified in a container on the dev server: setup, login, every page's
nav and active item, domain and application creation, all account-form
paths including cross-session invalidation, import errors, full backup
download. gofmt/vet/test/docker build green.
