I developed a leak in the lines of my AC system (verified). The system has been recharged so it is working for the time being, but I do not expect it to last indefinitely.

I am due to buy a new car, so I don't want to put money into a costly repair. So in terms of holding out as long as possible until I make that purchase… will the AC charge last longer if I only use it when absolutely necessary, or is the pressurized refrigerant (r134a) just leaking out constantly whether I use it nor not?

Depends entirely where the leak is, and what's leaking. If it's on the high side it's going to leak faster when the AC is used. If it's on the low side it's going to leak slower when the AC is used.

Since you are just trying to get by, and your getting rid of the vehicle soon you could top it off with the DIY AC charge kits sold at the local parts store with the following caveat DIY AC Recharging is not recommended
