Provide debit summary

[baccenfutter]

Calling https://vorstand.c-base.org/cteward-api/legacy/member/baccenfutter/debit/summary/ should return a nice summary of a member's debits. This improves performance as a client wouldn't have to fetch the entire list of entries to do the math locally. Additionally it should turn out to be much more human-parsable as a list of entries.

The result of such a call should look somewhat like this:

{
"total_payments": 0,
"total_bounces": 0,
"current_balance": 0,
}
