feat: display the current translating stuff in settings

 The Posts and Pages lists show a status column for every target language, including the latest successful translation time and a translation action. The Settings page also provides **重新翻译所有内容**. It shows a confirmation warning before scheduling a forced refresh of published posts, pages, categories, and tags; this bypasses persisted translations and consumes Baidu API quota.
 
+The Settings page also shows a live progress panel. It refreshes every five seconds and counts completed post/page and category/tag items for every configured target language. Progress reads only local WordPress and translation-table data; it does not send additional requests to Baidu.

 ## Known Limitations
 
 - The settings UI accepts language codes but does not yet validate them against a maintained Baidu language-code list.
