private/transfer_positions_debug

Takes the same params as private/transfer_positions and rebuilds both the maker and taker Actions without executing anything, returning for each side the EIP-712 encoded_data, encoded_data_hashed, action_hash, typed_data_hash, domain_separator, action_typehash, module, owner and expected_signer, plus the decoded action data (the maker's priced legs, and the taker's order_hash committing to them). Byte-compare these against your local computation to find why a signature is rejected. Requires a logged-in session; no transfer scope needed.
