A Rücklastschrift is still the member's own failure to ensure cover or provide valid bank details, so it belongs in the same escalation ladder as a regular reminder -- it now occupies whatever level the claim is next due for, alongside a "Rücklastschrift" preset next to the existing Mahnstufe presets. Mahnung vorbereiten no longer lets the board pick a level (it's computed automatically from what's already been sent, since the sequencing was already server-enforced) and replaces the single fee field with a small items table (Beschreibung + Betrag), so a reminder can carry several charges at once -- e.g. Rücklastschriftgebühr plus Bankgebühr plus Porto -- each landing on the claim as its own line item instead of one lump sum under a generic label. The description field offers the configured standard texts but stays free-editable. Those standard texts and amounts, plus the dunning levels themselves (name/fee/deadline), are now configurable from Optionen -> Mahnungen instead of only being editable by hand-editing repository.json, which was the case for the whole reminder policy until now. Cleaned up reminder_fee/failed_debit_fee on contribution rules while at it -- both were unused leftovers superseded by this. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
