Enhance exercise selection and display features

- Introduced new CSS styles for exercise cards and selection sections, improving visual feedback for selected exercises.
- Updated ExerciseListCard to support a new `selectionPinned` prop, allowing for a badge display on selected exercises.
- Refactored selection handling in ExercisesListPageRoot to manage selected entries more effectively, replacing the previous Set-based approach.
- Enhanced SaveSelectedExercisesAsModuleModal to support appending exercises to existing modules, improving module management capabilities.
- Updated session state handling to include selected entries, ensuring persistence across sessions.
