Offline signing command requesting local node

[dan-u410]

Some steps in the offline flow don't match the workflow I'm seeking:

Generation:

• This was workable, however, to avoid ever loading private keys to the online machine there's an extra step not noted in the docs:

namada wallet add --alias view-only-wallet --value <my-public-key>

• This might be helpful to add for others following this guide since the error message returned without this is very confusing at first

Signing:

I've configured my offline wallet with the secret keys necessary for signing, however it seems the node needs to be started locally to sign offline?

• the sign-tx command immediately checks for a node connection here but it looks like this is only used to look up the wallet context
• is there a way to pass in a wallet file or similar as an argument and forego any node requests when offline?

namadac sign-tx --tx-path transfer.tx --owner wallet1
Failed to query node status with error:
   0: HTTP error
   1: error sending request for url (http://127.0.0.1:26657/): error trying to connect: tcp connect error: Connection refused (os error 61)
....

Broadcast:

• I've gotten this working but there are some sharp edges that I wanted to note:
• i) this command wants to automatically submit a reveal_pk tx. However, this is not possible when the owner's private keys are not loaded onto the node. I am forking the SDK and removing this line from this command since I will issue the reveal_pk command indepdentely
• ii) This transaction needs to be signed by the gas_payer to be valid. This should be moved to the offline sign-tx command so private keys never needed to be loaded to the online machine

namada client tx --tx-path tx.tx --signatures sig1.tx --owner view-only-wallet --node https://rpc.luminara.icu --gas-payer view-only-wallet --force
Submitting a tx to reveal the public key for address <address>...
Error: 
   0: unable to sign transaction with <pubkey>
....

I am following the offline signing guide in the docs here
