feat(training-unit-editor): enhance combo planning features and UI updates

- Added a new function `compactComboPlanningCaption` to display planning status with archetype labels.
- Introduced state management for a modal to edit combination planning profiles, improving user interaction.
- Updated UI components to enhance the display and interaction of combination exercises, including styling adjustments for better usability.
- Implemented keyboard event handling for modal closure, enhancing user experience.
