Automatically repay the bank loan at the selected game hour.

If the available balance is at least $ 25.000 and there is an active debt,
the mod automatically repays the bank at month change and at 03:00,
returning only the money above the configured minimum in steps of $ 5.000
so the balance never drops below the chosen minimum.

Settings:
- Default repayment hour: 03:00
- Selectable repayment hour: 1 to 23
- Default minimum balance: $ 25.000
- Selectable minimum balance: from $ 10.000 to $ 200.000
