fix: use window.location.href instead of pathname to handle APP_BASE_PATH correctly (#17291)

[waterWang]

Fixes #17291

Problem

When APP_BASE_PATH is configured, clicking download on a document creates a URL with a duplicated base path (e.g., /opencti_dev/opencti_dev/storage/get/...), causing the download to fail.

Root Cause

The handleLink function in FileLine.tsx used window.location.pathname = url to navigate, which doesn't handle the base path correctly.

Fix

Changed window.location.pathname = url to window.location.href = url, which correctly handles both absolute and relative URLs.

Hey @waterWang! 👋 Thanks a lot for opening PR #17513 — really appreciate the fix, and welcome to the OpenCTI community! 🙏

I just had a quick look and I think the description could be enhanced a little to help reviewers get through it faster. I haven't changed anything in your description — just a gentle suggestion:

Area: How to test this PR
What could help: The template's "How to test this PR" section is missing entirely — there are no steps for a reviewer to reproduce the APP_BASE_PATH download issue and confirm the fix.
Suggestion: Add a short set of steps, e.g. "1. Configure APP_BASE_PATH (e.g. /opencti_dev). 2. Open a document and click Download. 3. Verify the URL is no longer duplicated and the file downloads correctly."

💡 If helpful, the CONTRIBUTING.md guide and PR template walk through what to include.

No rush at all — thanks again for contributing to the project! 🚀

Changes:

• Updated FileLine’s handleLink navigation from window.location.pathname = url to window.location.href = url to correctly resolve absolute/relative URLs under a router basename / base path.
