Add full hardware configuration for Legion Pro 7 16IRX8H including: - Realtek ALC287 + TAS2781 audio with proper kernel params - Bluetooth LE Audio support via BlueZ settings - Thermal management (thermald + ACPI fixes) - Audio group permissions Fixes audio issues where speakers wouldn't work due to missing TAS2781 calibration reset and incorrect HDA model detection.
