Update API Documentation and Enhance Tender Query Parameters

- Changed references in API documentation from `main.HealthResponse` to `bootstrap.HealthResponse` for consistency.
- Added new query parameters `publication_from` and `publication_to` to the tender listing and recommendation endpoints to allow filtering by publication date.
- Updated the `ListTendersRequest` struct to include optional fields for `from` and `to` timestamps.
- Modified the `TenderRepository` and `TenderService` interfaces to support the new filtering parameters in the tender listing functionality.
- Enhanced the service and handler layers to process the new query parameters, improving the flexibility of tender retrieval.
