Zepp OS: Enable workout detection sensitivity for Helio Strap

- Add supportsWorkoutActivityTypesConfiguration() to enable workout settings for devices without display
- Add supportsWorkoutDetectionCategories() to control visibility of workout categories
- Update ZeppOsSettingsCustomizer to hide workout categories preference for devices that don't support it
- Enable workout detection sensitivity configuration for Amazfit Helio Strap
- Workout categories selector is hidden for Helio Strap, only alert and sensitivity settings are shown
This allows the Helio Strap to configure automatic workout detection sensitivity despite having no display.
