fix(ipx): use the configured baseURL when prerendering static images

[chairulakmal]

🔗 Linked issue

resolves #1394

📚 Description

Prerendering skips every IPX image when you set a custom baseURL, because the filter in prerenderStaticImages hardcodes /_ipx/. I changed it to use the configured base URL and fall back to /_ipx, so nothing changes on the default. I also strip a trailing slash, since '/static-images/' would otherwise fail the same silent way.

I pass the base URL in from the three call sites, which all have it already, instead of reading it inside the util: the unit tests import src/runtime/utils/ too, and #imports does not resolve there. Also added a new test file, test/e2e/generate-base-url.test.ts, instead of editing the existing generate test, so the default path stays covered. It fails without the change.

The CI tests passed except the two aliyun e2e cases that time out for me locally because their host is unreachable from my network. This is the same as a clean main, so unlikely the result of my changes in this PR.

📝 Walkthrough

Walkthrough

The change passes the configured IPX runtime baseURL into static image prerendering from NuxtImg, NuxtPicture, and the image runtime. The prerender utility normalizes the URL and uses it to detect image paths instead of relying on /_ipx/. An end-to-end test verifies prerendering with /static-images.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to be994

This localized change uses the configured base URL for static image prerendering while preserving the default behavior, and no actionable merge-blocking risk remains after normal checks and review.
