feat: refactor ObjectivesBoard and enhance column visibility management

- Replaced local state management in `ObjectivesBoard` with `useObjectivesCollapse` hook for better state handling.
- Updated collapse button logic to use the new hook's toggle function, improving code clarity.
- Refactored `useColumnVisibility` to load user preferences on mount and persist visibility changes, enhancing user experience.
- Integrated user preferences for Kanban filters in `TasksContext`, allowing for persistent filter settings across sessions.
