ui: include warnings in polygon/ethereum/etc assets receive address modal about ensuring the correct network/contract is used

[bochinchero]

More to avoid confusion on the user end, particularly as more EVM assets/networks get supported, there should be warnings on the receive address modal to ensure the correct network/contract is used for every asset:

Binance, as an example, has warnings about the contract:

Good example of where this could cause issues is when receiving MATIC/POL, it doesn't state that it's on the Polygon network and someone could transfer the erc-20 from an exchange.

On a related note, I would suggest to not show this contract address like this because it creates wrong impression of being your wallet address (and not a contract address):

I would suggest hiding it under info tooltip.

+1.

Have had multiple users already message me saying they used the ETH network to send MATIC - losing their funds.
