DOMAIN_SUFFIX=local (or any non-localhost LAN name) caused a TLS handshake
failure because Caddy attempted an ACME challenge that can never succeed for
private domains.
- Caddyfile: tls {$ACME_EMAIL:internal} — falls back to Caddy's built-in CA
when ACME_EMAIL is absent, uses Let's Encrypt when it is set.
- start.sh: ACME_EMAIL is now optional; missing it prints a warning instead
of aborting, so local/LAN setups work without an email address.

- New HIY_ADMIN_USER / HIY_ADMIN_PASS env vars control access
- Login page at /login with redirect-after-login support
- Cookie-based sessions (HttpOnly, SameSite=Strict); cleared on restart
- Auth middleware applied to all routes except /webhook/:app_id (HMAC) and /login
- Auth is skipped when credentials are not configured (dev mode, warns at startup)
- Logout link in both dashboard nav bars
- Caddy admin port 2019 no longer published to the host in docker-compose

Without a fallback, an unset DOMAIN_SUFFIX expands to an empty string,
making Caddy parse the site block as a second global options block and
fail to start. Using {:localhost} defaults to localhost.
Caddy's email directive requires a non-empty argument. Since ACME_EMAIL
wasn't set, Caddy failed to parse the config. Email is optional for
Let's Encrypt — remove the directive entirely and document it as a
manual opt-in comment.
Caddy's built-in ACME support handles TLS automatically — no CF_API_TOKEN,
no Cloudflare account, no DNS plugin needed. Requires ports 80+443 forwarded
to the Pi and ACME_EMAIL set in infra/.env.
The Caddyfile created a server with an auto-generated name, not 'hiy',
so build.sh's PUT to /config/apps/http/servers/hiy/routes was creating
a parallel server that never received traffic.
- Replace Caddyfile with caddy.json that names the server 'hiy' with
the dashboard as a catch-all fallback route
- Insert app routes at index 0 so host-matched routes are evaluated
before the catch-all dashboard fallback
- Update docker-compose to mount caddy.json and pass --config flag
