Add keyboard shortcut support for service menu actions

Introduce ServiceMenuShortcutManager, which registers all service menu actions with KActionCollection at startup allowing users to assign keyboard shortcuts in Configure Keyboard Shorcuts. Save/Load of configs happens via KXMLGUI in dolphinui.rc.

Notes:
- Manager initializes before setupGUI() for shortcut restoration
- Execution and validation handled entirely by KFileItemAction in KIO.
