feat: add quick create draft functionality in ExercisePickerModal

- Introduced a quick create draft feature allowing users to create private exercise drafts directly from the ExercisePickerModal.
- Added state management for quick create inputs including title and summary, with validation for minimum title length.
- Updated the Dashboard to display a preview of private exercise drafts, enhancing user visibility of pending exercises.
- Enabled quick create functionality in TrainingFrameworkProgramEditPage and TrainingPlanningPage for streamlined exercise management.
