Hide site preview button if pages.preview permission is disabled

[lukasbestle]

Description

The site preview depends on the preview of the home page. If the pages.preview permission is disabled, the page preview button is disabled, but the site preview button is still there (but doesn't work).

Expected behavior

Site preview button should be hidden if pages.preview permission is disabled.

To reproduce

1. Disable pages.preview permission for current user role
2. Open form controls on site view
3. See preview button

Your setup

Kirby Version

v5/develop

Additional context

The following line is causing this:

kirby/panel/src/components/Views/Pages/SiteView.vue

Line 22 in ea833c3

:preview="api + '/preview/compare'"

The equivalent line in PageView.vue checks the permission:

kirby/panel/src/components/Views/Pages/PageView.vue

Line 26 in ea833c3

:preview="permissions.preview ? api + '/preview/compare' : false"

Note that:

• the preview on the site view currently succeeds even if the permission is disabled. This is fixed by Enforce pages.preview permission #7069.
• we cannot copy the code 1:1 as it's the pages.preview permission of the home page, not of the site.
