Extension: Display Tx details in Approval window for signing

We need to re-introduce details about the Tx being signed in the Approval views.

Extension will at the very least know what type of Tx is being signed for display purposes
Add a query to obtain Tx details from the PendingTx
Currently, extension receives serialized values for tx & signing data as constructed by build functions in the SDK. Is it possible to deserialize the Tx completely within the extension from tx solely?
Alternatively, we can pass the original Tx constructing args to this call to make them available to the extension, though if we can avoid that, we probably should, just to keep the API as simple as possible
Whichever values will be required should be wrapped in the type returned by the SDK JS package's buildTx functions, for simplicity's-sake. The TxType can be appended to the route used to invoke the approval, so we can use the enum value, e.g.: /approve-sign-tx/1/.... where 1 references the enum value, or /approve-sign-tx/transfer/...

The route could simply follow this structure:

/approve-sign-tx/{accountType}/{txType}/{msgId}

Where accountType determines whether we use Extension key store, or Ledger HW Wallet, and txType tells us how to deserialize & display the Tx, and msgId gives us the key for the PendingTx

Sign Arbitrary

We should handle "details" the same way when signing arbitrary data as well. We query the details for signArbitrary calls, which will always return a string. Then, attempt to parse the string as JSON, and format, something like:

try {
  const json = JSON.parse(data);
  const formatted = JSON.stringify(data, null, 2);
  setData(formatted);
} catch (e) {
  setData(data); // unchanged
}

And display in a <pre></pre> per the designs
