## **Description**

This pr adds a new QRWalletAdapter for QR code-based hardware wallet
support

There is no visual change for this pr. It will be enabled in subsequent
prs.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Adds a new hardware wallet adapter with camera-permission handling and
changes transport-monitoring behavior to support adapters that opt out,
plus upgrades `@metamask/hw-wallet-sdk`; issues would primarily surface
as connection/permission flow regressions.
> 
> **Overview**
> Adds a new `QRWalletAdapter` implementing the hardware-wallet adapter
interface for QR-based wallets, modeling “connection” as storing a QR
device/account id and gating readiness on camera permission (emitting
`DeviceEvent.ConnectionFailed` with `CameraPermissionDenied` when
denied).
> 
> Updates transport monitoring to **skip preflight/error UI** for
adapters that return `null` from `getTransportDisabledErrorCode()` (used
by QR to opt out of persistent transport checks), and extends error-name
mappings with QR-related error names.
> 
> Updates test infrastructure by enhancing the
`react-native-vision-camera` mock with static permission methods, and
adds unit tests for the new adapter and the transport-monitoring opt-out
behavior. Also bumps `@metamask/hw-wallet-sdk` from `^0.4.0` to
`^0.7.0`.
