router-webui (Go, standard library only) edits settings.json: host
name, WAN (DHCP or PPPoE), LANs with DHCP, and the raw JSON for the
rest; keys the forms do not know are kept. It applies and confirms by
starting router-apply.service and router-confirm.service, which a
switch never restarts, and shows the build log and the rollback
countdown. HTTPS with a self-signed certificate, a PBKDF2 password
hash, CSRF tokens and an Origin check; reachable from management LANs
only (new router.managementPorts).
router-apply records the settings it built and router-confirm keeps
them as settings.confirmed.json (new rollback.onConfirm hook), so the
UI can tell unapplied changes and discard them.
checks.apply now also logs in from a LAN client, discards the change
left by the rollback, edits the DHCP pool, applies and confirms.
