Remove manual paid_amount and fine inputs from retroactive wizard

These fields were editable, allowing users to accidentally set
paid_amount on 'overdue' rows (causing fine calculation to skip them).
Now paid_amount is always hidden=0 (server sets it for 'paid' status)
and fine shows "تلقائي" (calculated automatically by the system).
