## PR-Codex overview
This PR simplifies the `TWAutoConnect` component by removing the optional `accountAbstraction` prop and streamlining its usage in the `BridgeProviders` component.

### Detailed summary
- Removed the `accountAbstraction` prop from the `TWAutoConnect` component.
- Updated the `TWAutoConnect` function signature to only require the `client` prop.
- Integrated `TWAutoConnect` into the `BridgeProviders` component, passing the `thirdwebClient`.

## Summary by CodeRabbit

* **Refactor**
  * Streamlined the auto-connect component API so it only requires the client, removing an unused configuration parameter.
  * Integrated the simplified auto-connect into the app provider stack to ensure automatic wallet/client initialization earlier in the startup sequence.
