Fund Customer SCW (On-Ramp)
Credits a customer’s Smart Contract Wallet with USDC on Polygon PoS. This triggers an ERC-20 transfer from the Rach treasury EOA to the customer’s SCW address. Debits your internal tenant USDC balance atomically before dispatching — returns 402 if your balance is insufficient. Idempotent: supply a stable deposit_id to safely retry without double-crediting.
