Implement Abstracted ConnectedWallet operations to DWN API

[prnk28]

Description

All ConnectedWallet methods are abstracted over API Methods. DWN Service Worker is responsible for sending Server Side Events which are interpreted by HTMX.

New Methods

• getAuthInfo()
• estimateFee()
• broadcastTx()
• pollTx()
• broadcastTxSync()
• signArbitrary()
• signAndBroadcastTx()
