Fix overlay: always show buttons, restrict translation, fix save data

- Always show favorite/save-to-diary buttons (login check on click)
- Restrict translation editor to senior_editor/admin only (canManage)
- Fix save: map ingredient oil→oil_name for API, reload recipes after
- Ensures next open shows the saved data
