feat: add debriefing functionality and enhance training unit filtering

- Introduced a new filter option for listing training units to show only those with pending debriefs.
- Updated the dashboard to reflect changes in training unit statuses, renaming components for clarity.
- Enhanced the Training Planning Page to manage debrief completion status, including UI elements for user interaction.
- Improved API utility to support new filtering criteria for training units, ensuring accurate data retrieval.
