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

- Updated CSS for the combo planning strip to improve layout and visual consistency.
- Refactored `compactComboPlanningCaption` to simplify the display of planning status.
- Introduced a new utility function to infer advance mode from stored slot rows, enhancing profile handling.
- Improved merging logic for slot profiles to ensure accurate representation of advance modes.
