[BUGFIX] Show CSH popup window without backend frame

Since #94084 all module URLs are automatically framed by
the TYPO3 main controller whenever they are opened
in a Sec-Fetch-Dest aware request.

Use a non-module route for the popup window in order
to avoid the automatic re-framing.

Also hide the back-button in the popup window, as it would
cause the entire backend to be opened in the popup.
The shortcut button will link to the module-based
detail-action in order to show in regular module context.
