Carlen White 84813cc57e Debit Cards, Bank Account Disable, & Other Retrofits (#19411) 
* Split up the charging code to allow verifying account security alone.

* Using macro since a trader account can now be created on the first debit card for traders.

* Adds the new debit_card.dm

* Retrofit for vending machines to accept debit cards and no longer care for the name of the person for account verification, instead checks if the account number is the same and does a security check when applicable to verify.

* Charge flow retrofit

* Debit card retrofit

* Debit card retrofit

* Debit card retrofit

* Supporting get_card() proc that attempts to find cards on someone.

* Debit card retrofit

* Adds debit cards.

* Basic debit card graphic

* Debit card retrofit

* Can print debit cards from an ATM for $5

* Tweak to prevent searching without an account number.

* Moved creating a trader account to a macro.

* Using item's melt_temperature instead of a global

* Debit cards can be inside ATMs, heads get a department debit card in their lockers, and traders get debit cards on their shuttle computer.
And updated graphics.

* Swapped the \the around since it looked weird being the other way
And also added something to point out which card is being used for virtual wallets.

* 100% less loss of work

* Prevent only the presentace of a card counting as a card present

* Easter egg will use the old name instead of a fixed string

* Forgot a period

* Added FUN. Debit no longer requires a PIN at default security level.
Of course, this can be changed with the new global. Might consider a admin toggle.

* Renamed var to something more reasonable.

* Made the security checks more future safe.

* Accounts can now be disabled from a account database as an administrative disable or from an ATM as a user disable.

* You can modify security levels while disabled, but cannot downgrade to Zero

* Can now charge a card without enough funds provided the destination and source account is the same

* Disable link changes depending if the account is disabled or not

* Vending machines now prompt for PIN if attempting to enter edit mode.

* Define cleanup

* You can now define a authorized user on a debit card.
They are also recorded in the transaction log so you can figure out who spent all the money on pizzas.

* If a linked account gets disconnected for any reason a POS will default to the station account
Also shows the account name in the settings

* Supply and Order consoles can now read from a debit card

* Documentation tweak

* Forgot something

* Supply console now shows the cargo account if requisitions are on.
And mitigation against someone else using the console with someone else looking at it.

* Attempt to make less redundant code,
And added additional information to supply orders.
Reverting checking accounts only if the users changed. It'd cause a world of confusion if multiple people were working at the same terminal.
