Operations delivery app fixes and improvements (#21720)

A small bundle of fixes with what is displayed, as mentioned in the
changelog.

Notable changes:
- It is now possible to charge department accounts directly using it.
The one doing it is logged in the transaction log for that account so
command can still go and check it. This was a feature I have been
requested repeatedly to make by operations member, to help encourage
people to buy more things for their department. Only a hangar tech
should be able to change the account that is charged as well.
- The delivery and pay buttons are now separate in the delivery app,
permitting someone to pay without having it delivered, or have it
delivered without paying. This also fixes a bug that paying before it
gets shipped to the Horizon could get an order permanently stuck as
being shipped & paid but not delivered.
