fix: Correct feature flags for multiple PodModel entries

Remove false positive hasEarDetection from Beats Studio Buds and Studio Buds+ (neither has in-ear detection). Remove false positive hasVolumeSwipe and hasVolumeSwipeLength from AirPods 4 ANC (volume swipe is exclusive to AirPods Pro). Add missing hasEarDetection to AirPods Max, AirPods Max USB-C, AirPods Gen 4, Beats Solo Pro, and Beats Studio 3 (all have head/ear detection per Apple docs).
