Preview a bridge quote before depositing

Returns the fees and expected output for bridging amount of sourceToken from sourceChainId to the account's registered target, before any funds are deposited. The orchestrator quotes against the supplied amount as if the deposit wallet already held it; the result is indicative and may differ from the quote applied once a real deposit lands. EVM source chains only. Scoped to the caller's tenant.
