Create /sources Page to Track Data Sources

[kouloumos]

As part of our efforts to improve data curation, we need a clear understanding of our current data sources and the process for integrating new ones. The first step is to create a new page at /sources where we can monitor and manage our data sources more effectively.

Proposed Solution

Create a simple view, such as a table, that shows:

• Each data source
• The timestamp of when the source was last scraped
• The number of documents we have for each source
• [your suggestions]

We should be able to get this information by querying Elasticsearch.
