Subject: [PATCH] Normalize Ethereum bridge chain for USDC

Proof: Ethereum 1Click assets now persist bridge chain eth:1, the current BTC/USDC seed uses eth:1, and regression tests cover Ethereum and Gnosis bridge-chain normalization.

Assumptions: NEAR Intents bridge RPC expects eth:1 for Ethereum deposit and recent-deposit endpoints.

Still fake: live ETH-USDC fills are not proven yet; runtime validation must confirm inventory refresh and quote lifecycle after deployment.
