getStepTrackingPermissionStatus

Infers whether the user has granted read permission for step-count data.

Apple does not expose whether individual read permissions were granted or denied. This method works around that limitation by:

1. Checking whether the authorization dialog has already been shown.

2. If it has, querying HealthKit for step-count data over the past 7 days.

• If data is returned, read permission is effectively granted.

• If no data is returned, the user likely denied access (because virtually every Apple Watch generates step-count data).

when (AFHealthTracking.getStepTrackingPermissionStatus()) {
    HealthPermissionStatus.LIKELY_GRANTED -> { /* show step data */}
    HealthPermissionStatus.LIKELY_DENIED  -> { /* prompt to enable in Health app */}
    HealthPermissionStatus.NOT_DETERMINED  -> { /* call requestPermissions() */}
    HealthPermissionStatus.UNAVAILABLE     -> { /* hide step tracking UI */}
}
