refactor: send request information for bus debug

[limwa]

This PR sends more debug information to Sentry so we can understand what is going on with STCP's website on some occasions.

Currently, some requests to STCP fail because uni can't find a CSRF token on the website. With this change, we'll send the request body and URL to Sentry for further analysis.
