The .dev TLD has been HSTS preloaded in Chrome/Firefox/Safari/Edge since 2019.
Browsers silently redirect http://anything.dev to https://anything.dev before
making any network request. Since Caddy has auto_https off, all browser-based
access to .dev domains fails with a connection error even though DNS, routing,
and HTTP all work correctly (curl works; browsers don't).
- cell_config.json: domain "dev" -> "lan"
- Caddyfile: all http://*.dev blocks -> http://*.lan
- Corefile: dev zone -> lan zone (file /data/lan.zone)
- data/dns/lan.zone: new zone file (dev.zone removed live)
- test_wg_domain_access.py: remove hardcoded DOMAIN_IPS / .dev references;
read domain from /api/config at runtime so tests work with any configured TLD
