VSN-1935 : Use the starter's generic Excel import service to handle fuel consumption Import
- Use the starter's generic Excel import service to handle fuel consumption imports and associate each import audit with its consumptions
- add endpoints for paginated import history and detailed import view :
- Added two new endpoints: GET /imports → returns a paginated and filtered list of import history (ImportAuditDto).
GET /imports/{id} → returns detailed information for a specific import, including all related consumptions.
- Closes VSN-1905
