## PR-Codex overview
This PR enhances the `Page` component in the `in-app-wallets/users` directory by adding error handling for project retrieval and updating the `clientId` property passed to `InAppWalletUsersPageContent`.

### Detailed summary
- Imported `notFound` from `next/navigation`.
- Fetched the `project` using `getProject` based on `team_slug` and `project_slug`.
- Added a check to call `notFound()` if the `project` is not found.
- Updated `clientId` prop in `InAppWalletUsersPageContent` to use `project.publishableKey`.
