refactor(ui): enhance styling and structure of training unit sections and combination plan bracket

- Updated CSS for training unit sections to improve layout and responsiveness, ensuring combo planning strips are displayed correctly.
- Refactored CombinationPlanBracket component to accept additional class names for better customization.
- Removed unused functions and streamlined imports in TrainingUnitSectionsEditor for cleaner code.
- Reintroduced ExercisePickerModal with improved placement in ExerciseFormPage for better user experience.
