Proposed solution

signBlob method from keyAgent is now also wrapped, so that the auto-redirect to sign success state can be removed, this was prematurely removing password from memory which caused the blob not to sign

Testing

Execute at example.com in console

const api = await window.cardano.lace.enable();
const ownAddress = await api.getUsedAddresses();
const signedData = await api.signData(
        ownAddress[0],
        '66697865642074686520627567'
      );

Screenshots

Fixes #803

I spot one small think, but it's not a deal breaker :)
