Description

This PR fixes the issue where running the DSpace UI with the "custom" theme resulted in many features not working properly. The root cause was identified as the themed components having mismatched imports compared to their base components. The PR addresses this by ensuring that all themed components have the same imports as their base components.

Instructions for Reviewers

The changes made in this PR include:

• Ensuring consistency in imports between themed components and their base components.
• Verifying that all fixed components now work correctly in the custom theme.

Testing Instructions:

1. Enable the custom theme.
2. Build the UI in production mode using yarn build:prod and serve using yarn serve:ssr.
3. Access the homepage and ensure that all features are working as expected.
4. Repeat the above steps for individual item pages to ensure proper functionality.

Merging even though the Codecov check above failed. Codecov is having issues...there's a bug impacting a lot of builds from GitHub. See DSpace/DSpace#9503 (comment)
