- Late fee can now be a FLAT amount OR a PERCENTAGE of the invoice gross (crm_invoices_late_fee_type/_percent, migration 143; defaults preserve the current flat behaviour). - Fee is charged from the 2nd reminder onward and accumulates per fee-bearing reminder (2nd = 1×, 3rd = 2×), computed from the level so re-applying a level never stacks. New resolvePerReminderFeeMinor() shared by applyReminder + the payment-check fee preview. - Reminder ladder extended to 3 levels (caps raised in sendReminder + recordPaymentCheckAction); the built-in dunning flow now loops 3× (seed v3, re-seeds the disabled built-in on boot). - Settings UI: flat/percent toggle + percent field, and a prominent AGB callout — a late fee is only enforceable if the concrete amount is stated in the terms (Mara's wording), 'verify with your Treuhänder'. en + native de. The fee math is examples-only / Treuhänder-verify; issued invoices stay immutable (the fee is tracked in late_fee_amount_minor, not folded into the original total). Tests 17/17, tsc 0, build green.
