Investment trades are shown with incorrect currency when non-USD

[bennypowers]

Describe the bug
Israeli stocks are listed in shekels. Maybe lists their agora (==fractional shekel) value in dollars, then converts that dollar value to shekels in dashboards, grossly inflating the value of my portfolio (which would be fine by me if it was a reality outside the confines of my homelab, but y'know...)

So for example, the price of Poalim (POLI.TA) is 4645 agorot or 46.45 shekels (about $12). this is listed on my maybe instance as $4,645.00, which is siginificanly more expensive than $12

So from the outside it seems like there are two errors compounding here

1. Synth does not appear to know that TASE stocks are listed in agorot
2. The list price of TASE stocks are being accepted as dollars but without price conversion, just swapping the currency symbol.

To Reproduce
Steps to reproduce the behavior:

1. Set up a selfhosted instance
2. Add a Synth API key
3. Add an investment account
4. Add a purchase record for POLI (poalim bank)
5. See error

Expected behavior
TASE stocks should be listed in agorot, converted to shekels, and their values not subsequently taken as dollars.

What version of Maybe are you using?

Not sure if already known but the bug is not limited to just Israeli stocks, I am trying to add stocks from National Stock Exchange (India) and it assumes the prices are in USD instead of INR.

Looks like a maybe bug, I checked and synth API is returning correct currency.
