Enrichment "admonitions"

[mhluongo]

The EnrichmentService includes annotations about transaction requests and addresses. It should also include the idea of "admonitions" — annotations that the UI should show as warnings, perhaps even requiring a user to agree.

Some example admonitions.

• Warn before a user sends funds to an address that has no ETH balance and a 0 nonce #2346
• Warn before user interacts with contract that no user has ever interacted with before #2347
• If a user is sending funds to any contract directly — but especially an ERC-20 or NFT contract address — this is a mistake.
  • Warn before allowing a user to send ERC-20 tokens or ETH directly to a contract #84
  • Warn before sending funds to a known ERC-20 contract #261
  • Warn before sending funds to a known contract #262
• If a user is approving a token spend to an EOA, it's likely a scam
  • Warn user before signing a token approval to an EOA #509
