change the MOD store currency icons

the episode shipment currency and the ship currency are too similar to each other, and the fact that the episode currency is not shown alongside the credits and ship currency to track what you have available to spend means accidentally spending the wrong currency.

this was already raised in the SWGOH reddit 5 months ago and no changes have been made since to improve visual clarity for the currency you are using.

you spend time and resources to redesign the entire cantina but can't do simple things right.
