Past Events Archive: Add Sort by Date and Search Functionality

[sklasfeld]

Description: Currently the past events archive has no way to sort or filter events, making it harder to navigate as the archive grows. Two improvements would greatly enhance usability:

1. Sort by Date: Add a sort button that allows users to toggle the past events archive between ascending and descending order by date.

2. Search Bar: Add a search bar that filters events by title and tags, similar to the existing search functionality on the blog page.
