Subject: [PATCH] Fix export: use Tauri save_file instead of blob, text button
 labels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Export was broken on Android — blob download (URL.createObjectURL)
doesn't work in WebView. Now uses Tauri save_file command which
triggers SAF file picker (same as GPX export).

Replaced cryptic arrow icons with readable text: "Импорт" / "Экспорт"
on both recipes and supplements screens.
