Spiked #150 against the AOSP Settings source (not just the reference docs): no
public, non-hidden Settings action opens the "Unrestricted/Optimized/Restricted"
screen directly for a specific package. ACTION_VIEW_ADVANCED_POWER_USAGE_DETAIL
would, but it's @hide/non-SDK; the other public battery action,
ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS, isn't package-scoped and is a worse
landing for one known app. So ACTION_APPLICATION_DETAILS_SETTINGS (one tap from
the target via "Battery" on stock/Pixel/AOSP) stays the primary target.
BatteryOptimizationManager.settingsIntent() is restructured into a verified,
never-dead-end fallback chain: try app-details, and if it doesn't resolve on
some device, fall back to the battery-optimization list rather than nothing.
The ordering/selection logic is extracted into a small Android-free helper so
it's directly unit-testable; a new instrumented test checks the real candidate
intents/order against a real PackageManager.
