feat: Add table aggregation endpoint for data summarization

- Implemented a new endpoint to retrieve aggregated data (SUM/COUNT) for specified columns in a given table.
- Added validation to ensure the presence of table name and valid aggregation columns in the request.
- Integrated company code filtering to restrict data access based on user permissions.
- Updated the table management routes to include the new aggregation functionality.
- Enhanced the frontend order page to utilize the new aggregation endpoint for improved statistical reporting.
