Update dependencies and enhance tender approval status handling

- Updated `pubspec.lock` to reflect new versions for several packages, including `async`, `fake_async`, `leak_tracker`, and `vm_service`.
- Modified `TenderApprovalStatus` enum to include a new status `approved`.
- Updated routing for `YourTendersRouteData` to accept a status parameter and pass it to the `YourTendersScreen`.
- Adjusted API calls and view models to utilize the new status handling, ensuring proper filtering and display of tender data based on approval status.
- Enhanced filter dialog to support new status options and improved user feedback in the UI for submitted and approved tenders.
