Description

• Public link root keeps the server URL: listFiles now passes the WebDAV base URL when it builds the public link space, so the space upserted after the password prompt keeps absolute WebDAV URLs and uploads no longer go to the web origin.

Related Issue

• Fixes Uploading into a password-protected link right after entering the password fails when web and server run on different origins #3668

How Has This Been Tested?

• test environment: unit tests (Vitest)
• test case 1: listing a public link root returns a space whose getWebDavUrl points to the server origin
