Management classes to php8.2

issue #6151

This replaces save_object and execute methods by 3 methods:
readPost - Reads POST data
update - Update object state
render - Render HTML UI

The point is to avoid reading POST and rendering HTML when this is not
 needed (when doing stuff through the webservice for instance).

It’s also more consisent across FD with all classes handling some kind
 of dialog implementing the new interface FusionDirectoryDialog which
 makes sure these 3 methods are implemented.

issue #6072

issue #5966

Added a ManagementDialog class to be used as a base for Dialog class
 intended to be used in a Management class.
Use it for snapshot dialogs and configuration dialog.
Sadly it could not be merged with GenericDialog because of slightly
 different workflows.
