- Add 409 conflict handling for duplicate iFlow config files
  - Add key creation hint in cookie login section
  - Move extra actions button after delete button for consistency
  - Improve OAuth status badge display logic (hide when idle)
  - Add config toggle enable/disable i18n translations
  - Adjust item-actions spacing from sm to md
