DataSource: Replace individual buttons with dropdown menu in EditDataSourceActions

- Convert LinkButton components to dropdown with Menu.Item components
- Add conditional rendering: show simple button when only one action, dropdown when multiple
- Use LinkButton for navigation and Button with dropdown icon for menu trigger
- Replace Trans components with t() function calls for Menu.Item labels
- Prevent PageHeader crowding when multiple plugin extensions are registered
- Maintain all existing functionality and tracking calls
