feat: pxeless playground + embedded wallet

First iteration of the PXEless playground. In order to restore full functionality, it makes use of an `EmbeddedWallet` which besides implementing the `Wallet` interface allows for the creation of accounts from the app.

The databases have been separated into two, a `PlaygroundDB` which contains purely application data and a `WalletDB` that stores accounts and other misc artifacts related to wallet operation.

The `Wallet` interface has been extended with account retrieval, and contract registration an updating has been simplified into a single method.

 Initial version of an "everything app" that can be used to test and benchmark Aztec.
 
-  * PXE in the browser with client proofs
-  * Connect to local sandbox or any network (scoped data)
-  * Lazy loading of most assets (think contract artifacts) and WASM (bb still loads at start due to top-level await, but in parallel as it is separated from the main index,js)
-  * Bundled by vite, 1MB compressed
-  * Drop any contract artifact, interpret its ABI, simulate and send
-  * Acts as a barebones wallet, managing auth scopes and separating accounts
-  * Stores artifacts, accounts and all that's required to pick up where you left off without having to redeploy everything (indexeddb)
-  * Supports basic aliasing of addresses
-  * Allows loading an artifact, provide the address and go (instead of having to deploy it)
-  * Add senders/contact management
-  * Authwits
