- Fix#2: Move DDNS bearer token from cell_config.json to data/api/ddns_token.
Token is now in the secrets store (data/) rather than the config store (config/).
Auto-migrates existing installs on first access. ConfigManager.get/set_ddns_token()
added. set_ddns_config() now strips 'token' key to prevent it leaking back.
- Fix#3: Set Caddyfile permissions to 0o600 after write so the token embedded
in the Caddyfile is not world-readable on the host filesystem.
- Fix#5: Heartbeat now fires IDENTITY_CHANGED after re-registration so Caddy
regenerates its config with the new token automatically — users no longer need
to click Re-register in Settings after a wizard registration failure.
Also: heartbeat skips the 401-cycle when no token exists and goes straight to
registration instead. DDNSManager now accepts service_bus= and is wired up.
- Fix#6: Settings page starts polling GET /api/caddy/cert-status every 15s
after a successful DDNS re-registration and shows "Acquiring certificate…"
feedback until Let's Encrypt issues the cert (up to 5 minutes).
- Fix#7: regenerate_with_installed() is debounced (5 s window) so two rapid
IDENTITY_CHANGED events (e.g. wizard + heartbeat) can't start simultaneous
ACME orders that interfere with each other.
