- DDNSTokenExpired exception triggers auto re-register in update_ip()
so cells recover silently after a DDNS DB reset
- POST /api/ddns/register lets the user force re-registration from Settings
- Re-register button in Settings → External Domain & DDNS (pic_ngo only)
- 3 new tests covering register endpoint: wrong provider, missing name, success

- GET /api/config now returns domain_mode, domain_name, ddns.{provider,subdomain,has_token}
- GET /api/ddns/check/<name> proxies availability check to DDNS service
- PUT /api/ddns validates and saves cloudflare/duckdns credentials post-setup
- When cell_name changes for pic_ngo provider, auto-registers the new subdomain
- Settings: Cell Name shows availability badge for pic_ngo; auto-save blocks on taken
- Settings: new External Domain & DDNS section — pic_ngo info, cloudflare/duckdns edit
- 11 new tests for the two new endpoints (all pass)
