## PR-Codex overview
This PR focuses on enhancing the transaction handling in the `Chats` component by improving the transaction execution process and ensuring the use of an authenticated `ThirdwebClient`.

### Detailed summary
- Updated `client` initialization in `ChatPageContent` to include `props.authToken`.
- Introduced `ExecuteTransaction` component to handle transaction execution.
- Replaced `SendTransactionButton` with `ExecuteTransaction` in `Chats`.
- Refactored `SendTransactionButton` to use `useSendTransaction` instead of `sendTransaction`.
- Simplified error handling for transaction data parsing.
