Bug 39236: writeoff_debts.pl needs adjustments

From bug 22435 - we need to use 'CREATE' as the account_offset type
From bug 31095 - we need to 'use Koha::Patrons;'

To test:
1 - Add a fine to a patron account
2 - perl misc/cronjobs/writeoff_debts.pl -v -c --added-after 2025-01-01
3 - Cronjob dies
4 - Apply patch
5 - Rerun
6 - Job succeeds!
7 - Confirm patron's fine is written off
8 - Sign off
