Update MongoDB Driver and Configuration for Company Entities

- Updated the MongoDB driver from v1.17.4 to v2.3.0, ensuring compatibility with the latest features and improvements.
- Refactored company-related entity and repository files to utilize the new driver, replacing `primitive.ObjectID` with `bson.ObjectID` for ID handling.
- Adjusted the configuration in `.drone.yml` to include the `main` branch in the trigger settings, enhancing CI/CD pipeline flexibility.
