refactor: update NVIDIA System-Assist client initialization and error handling (#8278)

Browse source 
* refactor: Improve NVIDIA System-Assist client initialization and error handling

- Updated the `maybe_register_rise_client` method to enhance error handling and remove unnecessary context management.
- Clarified the component description to specify Windows-only support.
- Improved input prompt information with an example for better user guidance.

* refactor: use constant for rise_initialized key in NvidiaSystemAssistComponent

Replaced hardcoded string with a constant for the rise_initialized key to improve code readability and maintainability.
