Expand the example for write scope

[sidko]

We need to expand the scope of the sample client example to include write scope.

As part of this issue, we will only test the internal send flow. The user workflow is as follows: I should be able to connect my Roll account to the client-example, approve the permissions, and then tip a user.

The following need to be tested:

• If the user denies access to client-example, the client-example should not be able to send any social money.
• The client-example should not be able to send social money on behalf of a user before going through the permission flow from the user.
• The client-example should not be able to send in excess of the daily limits for the user.
• The client-example should be able to send social money after the 24 hour period has elapsed for the daily limits.

The following components are needed on the UI:

• Pre-fill some accounts for the user to tip to - Bradley, Sid, Marlon, Ashish, Gaurav, Sinkas to start with.
• Let the user specify the recipient, token, and amount.
• Throw the message received from the server to the frontend
