Enhance ProviderSettings component with loading state and improved UI interactions

- Introduced a loading state to indicate when a provider is starting, enhancing user experience.
- Disabled radio buttons and action buttons during the loading state to prevent user interaction.
- Updated UI elements to reflect the loading state, including a spinner and appropriate cursor styles.
