Breaking: Images render as a responsive picture

Description

The program list item and the program page template render their image through the responsive image partial of EXT:academic_base, Partials/Academic/Image.html, from 3.0 on. Every raster image is therefore a <picture> with WebP sources and a fallback <img> with the class ace-image of the partial, and an SVG file is rendered as one <img> of the original file without processing.

The list item asks for the preset card, the page template for detail.

The views register EXT:academic_base/Resources/Private/Partials/: the plugin view with the partial root path key -1, below the keys 0 and 1 it uses already, and the page object of the program page type with the key -1758484802, below every theme and project path. The page object registers it twice, because a PAGEVIEW page object reads no partialRootPaths: it derives those from paths by appending Partials/, so paths carries EXT:academic_base/Resources/Private/ under the same key.

Impact

CSS that selects the image as a direct child of the card, or as the direct child of the detail container, no longer matches: it is wrapped in a <picture>.
The fallback image is requested with loading="lazy", which it was not before, and its width and height are those of the preset rather than those of the original file.
A project that replaces the partial root paths of the plugin completely, or a page object that renders Program/Item or the page template in a view of its own, fails with an exception on the partial Academic/Image that the view cannot resolve.

Affected Installations

Every installation that renders a program list, or a page of the program page type with an image.

Migration

Adjust CSS that addresses the program image.
A plugin view whose partial root paths were replaced needs the path of EXT:academic_base below the others:
```
plugin.tx_academicprograms.view.partialRootPaths {
    -1 = EXT:academic_base/Resources/Private/Partials/
}
```
Copied!
If a page object of the project renders the page template or one of the item partials itself, list the path there with a key of your own - under partialRootPaths for a FLUIDTEMPLATE page object, under paths for a PAGEVIEW one:
```
page.10 {
    partialRootPaths.-1700000001 = EXT:academic_base/Resources/Private/Partials/
    paths.-1700000001 = EXT:academic_base/Resources/Private/
}
```
Copied!
Flush the TYPO3 caches, so the Fluid template cache is rebuilt.
