feat: add user preferences for filter and objective visibility in HomePageClient

- Implemented state management for filter and objective visibility using `useState`.
- Integrated `userPreferencesService` to load and save user preferences on component mount and toggle actions.
- Updated `KanbanBoardContainer` to conditionally render filters and objectives based on user preferences.
- Enhanced UI with buttons for toggling visibility, improving user experience and customization.
