Add an option to app.getImageBaseURL() to return an absolute URL (not only a relative path)

In Domino Leap, the function app.getImageBaseURL() always returns a relative URL, as documented.

However, App Page Image components (setURL()) require an absolute URL. They do not accept relative paths in either secure mode or non-secure mode.

This creates a functional gap:

Developers cannot obtain an absolute URL for application‑embedded images,even though absolute URLs are required by the Image component.

As a result, dynamic image switching using application‑stored images is currently impossible.

Steps to reproduce:

1. Deploy an app with images stored in the application

2. Call app.getImageBaseURL()

3. The function returns a relative path (e.g. ../../../../../anon/.../image/)

4. Call appPage.F_Image.setURL(base + "icon.svg")

5. The image does not load because setURL() requires an absolute URL

6. There is no API to convert the relative path into an absolute one

Request:
Please add a way for app.getImageBaseURL() to return an absolute URL, so that images stored in the application can be used with setURL() on App Page Image components.
