Lazy loading for Apps/Charts page #16040
Description
The Apps/Charts page by default has around 140 charts, and by adding new repositories, this number can grow significantly. This currently leads to performance issues, including slow initial page loads and unresponsiveness. While the best long-term approach would be a lazy loading mechanism integrated with backend support, having server-side pagination for charts can take a long time to implement. We can still greatly benefit from a completely client-side lazy loading solution in the meantime.
