Issue Number (if Applicable): Fixes #

Description

Adds several UI improvements to EVM wallets.

• The balance card can be configured to show any EVM token, or show a combined fiat balance.
• The transaction history now shows currency icons.
• The assets section has been reworked with the more compact design.
• The asset details now show the currency ticker instead of the chain ticker.

Also includes .svg versions of crypto icons - UI can be adapted to use these later for better performance.
