Design way to differentiate network icons

[kevinghim]

Description

Users have 3 ways to add a network:

1. Select a popular hardcoded network
2. Go to dapp and Select Add to MetaMask, dapp then uses addEthereumChain
3. Add a network manual

Icons for chains added through 2, and in the future possibly through 3, can conflict for different reasons:

• Same chainID, different RPC, similar or identical icon
• Different chainID, different RPC, similar or identical icon (scam chain)

User story

As a user I want to be able to recognise each chain by a unique property, because

• I want to prevent confirming transactions on a chain that looks the same but has a different ID
• I want to prevent connecting to a malicious RPC endpoint that logs my IP along with blockchain interactions

Technical Details

Acceptance Criteria

Users can visually differentiate each chain entry (RPC + chainID combination)
