Feat Request: Overwrite default currency

[cmergenthaler]

Is your feature request related to a problem? Please describe.
The default currency is USD which is hardcorded in https://github.com/opencost/opencost/blob/develop/ui/src/Reports.js#L128

Describe the solution you'd like
Let us somehow overwrite the default currency by e.g setting an environment variable.
I'd be happy to file a PR if this is an accepted solution

Describe alternatives you've considered
Always needed to change to my local currency from USD is inconvenient.

That sounds like a nice feature to add. A PR against the UI as an environment variable would make sense. Thanks!

@mattray ...can I work on this?

[mattray]

@jash2105 definitely, we're happy to take PRs. I'll keep an eye out for it

The currency change just misleading. The drop down to change the currency simply changes the symbol associated with COST and does not apply the conversion rate or ask for conversion rate to apply.

USD 300 != INR 300
