Refactor tender approval logic to streamline submission mode handling

- Removed the resetting of `SubmissionMode` in the `Reject` method of the `TenderApproval` entity, ensuring that the submission mode is preserved upon rejection.
- Updated the `GetCompanyTenderApprovalStats` method in the repository to count submissions by mode without filtering by status, enhancing the accuracy of statistics.
- Adjusted the `ToggleTenderApproval` method in the service to set the `SubmissionMode` when rejecting a tender, ensuring consistent handling of submission modes across approval states.

This update improves the clarity and functionality of tender approval processes, ensuring that submission modes are correctly managed during approval and rejection scenarios.
