Subject: [PATCH] fix: external knowledge citations show the domain instead of
 the page title (#31982)

The inline citation markers in answers from external knowledge bases (Qdrant, Milvus, pgvector) showed the site's domain, for example docs.example.test, instead of the page title saved with each document. They now show that title, the same way a regular knowledge base shows the file name, and still fall back to the domain when a document has no title. Two different pages can share a title, so each marker now looks up its title by the page it points to; before, a repeated title made every later marker show the next page's title and the last one show nothing.

Fixes https://github.com/open-webui/open-webui/issues/31929
