feat(dashboard): refactor home page to utilize TenderDashboard component

- Replaced the previous home page structure with a simplified TenderDashboard component for improved clarity and maintainability.
- Updated the .gitignore file to include IDE-specific files, ensuring a cleaner repository.
- Enhanced the useTenderListPresenter to support new parsing logic for cpv_codes in search parameters.
- Introduced a new utility function, buildQueryString, for better handling of query parameters in API requests.
