fix: service edit, CSRF token stability, and license restore (v1.1.1)

- Fix service edit double-write bug (was creating duplicate entries)
- Add editable display name field to service edit modal
- Backend update endpoint now accepts name, logo, and recalculates url
- Fix CSRF token regeneration breaking all POST requests (nonce was
  being regenerated on every request, invalidating cached tokens)
- CSRF nonce now persists across requests, rotated only on TOTP login
- Frontend secureFetch auto-retries on CSRF failure with fresh token
- Restore lifetime license activation on DNS2
