CSR ignores namespace configuration causing broken resource loading

[milanmajchrak]

Describe the bug

DSpace 7.6.5.
When DSpace is configured with a namespace (e.g., /repository), Server-Side Rendering (SSR) correctly handles the base href, but Client-Side Rendering (CSR) serve the original index.html with <base href="/">, causing the browser to request JavaScript resources from the wrong path.

To Reproduce

1. Configure DSpace with ui.nameSpace: /repository
2. Exclude SSR for the ^/search$" page
3. Go to the /repository/search and refresh the page

Expected behavior

The search page should load, but instead a blank page is displayed.

@milanmajchrak : Do you happen to know if this also impacts 8.x and 9.x? Or is this specific to 7.x
