Warning required on /admin/#stats

[ghost]

Description

The Disk usage functionality is a convenient way to analyze how CryptPad is using the server's storage. However, when it's using a lot of space, clicking the "Generate report" button can lead to consuming all the memory available on the machine. Having the CryptPad process running out of memory and crashing.

We should add a short warning message when clicking the button explaining this and asking for confirmation.

This could be something like this:

Depending on the size of the data stored on your instance, generating this report can consume all the memory available on your server and lead to a crash. Use with caution!

1. Head over /admin/#stats
2. Scroll down the page
3. Click "Generate report"
4. Have your instance crashing
