WEB: Unable to set prices with more than 4 decimals

**Description**
In normal circumstances you don't need/have to set more than 4 decimals for the price, but with cryptos like SHIB you do.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to https://app.alpaca.markets
2. Create a Limit Order for SHIB/USD
3. Try to set the price to 0.000013

**Expected behavior**
It should allow us to enter more than 4 decimals in this case.
