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were unused leftovers superseded by this.
