Hit a roadblock in the p2pk betting.

Need to get a nostr sig on a proof secret string, preferably with a browser extension/signing app, but AFAIK they only sign full nostr events which won't satisfy the proof witness sig

So the current plan is to embed hidden nostr pub/private keys in localstorage so I can validate the system works at all

Then get the extension/app signer to sign a string so you don't have nsec in localstorage and
