dolphinmainwindow: Reload context menu plugins when configuration changes

Reload the context menu plugins and share the KFileItemActions with the context menu so it stays up-to-date as the user changes the service menu settings.

This uses a KConfigWatcher to trigger settings reload on "kservicemenurc" changes, covering both internal settings changes and external scripts.

Remove the obsolete restart prompt in ContextMenuSettingsPage since changes are now applied instantly.
