FR: change default currency symbol

[Szeraax]

I don't know the best approach, but at current, I'm entering USD ($) into the amount field, but the label specifies euros. I don't need to enable tracking of multiple currencies to each person, but you may want to go that direction in the future (assuming you want to avoid any stuff with currency conversion).

Maybe a simple ENV variable could define what currency symbol to use. Maybe get rid of a currency symbol altogether. Again, dunno.

Adding an env for the default currency seems like a good option for now 👍

I thought some more about this, and I thing, it should be done per group.
There can still be an environment variable to select the default.
