Reload on Scroll

Description
The application currently does not reload content when the user scrolls down. Implementing a reload on scroll-down functionality can improve the user experience by ensuring updated and dynamic content is displayed.

Expected Behavior:
When the user scrolls down to the top of the page, the application should trigger a refresh or reload to display the latest content.

Describe the solution you'd like

Implement a "pull-to-refresh" mechanism where scrolling down from the top triggers a reload.
Add a visual indicator (e.g., a spinner or progress bar) to show the reload action is occurring.

The issue names no files, tests, or entry points. First locate the frontend scroll handling and content-loading entry points, then check how the application represents loading state. Done means pull-to-refresh from the top reloads current content and exposes a visible reload indicator, with the relevant behavior covered by existing tests if available.
