Switch current USDC route to Ethereum wrapper

Proof: current BTC/USDC route seeding now targets the live Ethereum USDC wrapper; tests cover ETH-USDC route activation and prove Gnosis USDC no longer receives the automatic BTC/USDC route.

Assumptions: the live NEAR Intents quote stream is emitting nBTC with Ethereum USDC, and Ethereum USDC uses bridge chain eth.

Still fake: no live ETH-USDC solver fill is proven yet; Gnosis USDC may remain imported for visibility but is not intended as the active BTC/USDC trading wrapper.
