Create Crypto Currency/Token balance component - embedded view

[dnaidionov]

The component represents the embedded view of the balance of Currency or Token (currently only ETH, ERC-20 or ERC-777 will be supported) at the specified address. Embedded view specifies:

• the Currency or Token, with Logo
• Address or ENS name
• Balance. If balance is more than 12 characters long, we reduce the font size to accommodate additional numbers. Long balances can break line an carry over to the next line if necessary (see designs)
• USD equivalent (if known) as of current date
• shortlist of available actions

Background of the card depends on the account's network:

• accounts on mainnet may have custom designs
• accounts on testnets have bright-colored backgrounds with testnet name spelled across the card background. This is done to easily visually distinguish testnet assets from the mainnet ones.
