minimum support for account witness verification & storage based on bisq

Browse Source 
verify peer witness data and share with arbitrator for signing
arbitrator can sign witness hash, owner pub key (see developer-guide.md)
taker signs offer id nonce in SendOfferAvailabilityRequest
maker signs deposit tx hash in SendSignContractRequest
buyer verifies witness with payload on deposit confirmation
seller verifies witness with payload on payment sent message
add synchronization to User paymentAccountsAsObservable and elsewhere

9. Run the tests with `npm run test -- -t 'my test'` to run tests by name and `npm test` to run all tests together. Ensure all tests pass and there are no exception stacktraces in the terminals of Alice, Bob, or the arbitrator.
10. Open pull requests to the haveno and haveno-ts projects for the backend and frontend implementations.
## How to manually sign accounts as the arbitrator
1. Open legacy UI as the arbitrator.
2. Go to the 'Account' tab.
3. Open Signing tab: `ctrl+i`
a. Sign payment account: `ctrl+s`, select payment accounts to sign (sourced from disputes).
b. Sign account age witness: `ctrl+p` then enter <witness hash>,<pub key hash> (from past trade details) and click the "Import unsigned account age witness" button.
c. Sign unsigned witness pub keys: `ctrl+o`
