Prepare a native transfer from a 2-of-3 Safe

Changed on

Runs the owner's send gates (wallet access, the sanctions screen on the destination, spend policies, Cedar/OPA transaction policy and treasury_send M-of-N consensus), then fixes a SafeTx: a native transfer (no calldata, operation 0, positive value, not to the Safe itself) at the Safe's current nonce (0 while undeployed). Returns its EIP-712 SafeTx hash (Safe v1.4.1 domain: chainId and verifyingContract; gas fields zero). The device recomputes the hash from the fields, confirms it pays exactly what was asked, signs it with D after a passkey touch bound to it, and calls execute. ERC-20 and contract calls are refused on this path.
