feat: enhance task forms and Kanban components with dynamic priority loading

- Updated `CreateTaskForm` and `EditTaskForm` to load priority options dynamically using `getAllPriorities`, improving maintainability.
- Refactored `KanbanFilters` to utilize dynamic priority options, enhancing filter functionality.
- Modified `QuickAddTask` and `TaskCard` to display priorities using centralized configuration, ensuring consistency across the application.
- Introduced new utility functions in `status-config.ts` for managing priority configurations, streamlining the task management process.
