Adds "Department Budget" access that lets you place orders with the shopping app, gives it to warden and cargo techs (#94288)

## About The Pull Request

The "NT Shopping Network" app now checks for if you have "Department
Budget" access instead of command access for letting you place orders
and not requests. All heads, cargo techs and the warden have it shift
start but it can be given to anyone (same as EVA access) and heads of
staff can add or remove it at their access consoles.
Also makes warden start with the app to hint that they have access to
the budget.

## Why It's Good For The Game

The access itself is good because letting heads choose who has access to
the department budget is obviously good.
Cargo techs get it cuz they already have access to it by having access
to the request consoles in cargo.
Warden gets it by default because HOS is usually busy
killing/arresting/patrolling while warden is the one actually managing
brig and the armory. If HOS really hates that warden has access to the
budget they can just remove it on their console.
