v2.5 — Default AMM

WUSDC Handling

Arc Testnet's native USDC (0x3600...0000) is not directly compatible with the AMM contracts. The DEX wraps it as WUSDC for pool interactions. ThegetDisplayTokenAddress utility maps WUSDC back to native USDC for display purposes, so users always see "USDC" in the UI.
