Update rank field type in tender and onboarding response structures

- Changed the `Rank` field type from `string` to `int` in the `RecommendedTenderResponse` struct within the `company` domain for better data representation.
- Updated the `Rank` field type from `string` to `int` in the `TenderResponse` struct within the `tender` domain to ensure consistency in ranking data.
- Modified the `Rank` field type from `string` to `int` in the `RecommendedTender` struct within the AI summarizer package to align with the updated data structure.

This update enhances the data integrity and consistency across the tender management system by standardizing the rank representation as an integer.
