endless scrolling for audits

[YtvwlD]

The audits page takes a long time to load.

Perhaps we could just load the last 50 audits initially and load the rest later on.

(API clients can and should only request the data they need.)

The audits page takes a long time to load.

Now, it's so bad that it doesn't load anymore.

The audit page has not been properly implemented. Because of the bad performance, I consider it a security issue, because it makes the application backend very vulnerable to denial-of-service attacks.
