Claims could previously only be cancelled (stornieren), which blocks once a
payment is allocated. Add a hard delete that releases any linked
payments/credits back to being unallocated instead of destroying them.
Payments could only be created from within a claim, forcing immediate
allocation. Add a bare payment creation flow in the Zahlungen tab so
incoming transfers can be logged first and allocated later.
Add a per-member Spenden tab (donations, backed by a new donations list on
ContributionData) so amounts paid beyond the membership fee can be tracked
and existing free payments allocated to them.
