wallet/signTransaction
Takes in an unsigned transaction and signs it with the wallet's spending key. You do not need to specify the account, the RPC will iterate through all accounts to find the one that can sign the transaction.

You can use the addTransaction RPC to add the signed transaction to the wallet and mempool.
