Hardware wallets

A long-term project, inscribing periodically, with the Parent inscription hot in the ord wallet is frightening.

Feature request: Ord builds the tx, without signing privileges, as a watch-only wallet.

I'm aware that Bitcoin Core manages the wallet file. I found this regarding signing tx outside of Bitcoin Core:

I am a photographer building a camera that stores the private key. I would like the tx to be a QR code so that I can sign with my lens. Ordinals has great potential for artists and I am very excited - thank you to everyone building.

I think we definitely want to support this. I'm laying the ground for this by converting our Bitcoin Core wallet to a BDK based wallet in #4252
