Implement Data Fetching for UPSA Partners Section from API

[Alina-Khmilevska]

The UPSA Partners section on our webpage needs to be dynamic. We aim to retrieve the data for this section from our backend API endpoint /upsa-api/partners.

Acceptance Criteria:

• Use the API endpoint /upsa-api/partners to fetch event data.
• Ensure that each event card displays the following details:
• Partner's image
• Link to partner's website
• The partners cards should be updated automatically with the latest data from the API.
• Implement error handling for the API call.
• Ensure responsiveness and maintain the styling as per the design specifications.

Data for the slider is dynamically pulled from Drupal via the API at /upsa-api/partners. All API calls have been tested and are functioning properly, with data loading and displaying without delays.
