Enhance tender and company context handling with new features and error management

- Introduced `PickAssignedCompanyID` function to determine the appropriate company ID for company-scoped operations, improving company assignment logic.
- Added `ResolveMongoID` method in the tender service to map MongoDB IDs and AI procedure references to canonical tender IDs, enhancing ID resolution.
- Updated `ToggleTenderApproval` to handle company ID validation and improve error handling, ensuring robust processing of tender approvals.
- Enhanced logging for error scenarios in the tender approval service, providing better insights into failures during operations.
- Refactored the `GetByID` and `GetByTenderAndCompany` methods in the tender approval repository to utilize custom error types for improved clarity.

This update significantly improves the handling of company and tender operations, enhancing error management and overall service reliability.
