feat: 系统控制模块 - 硬件抽象层

新增： - ScreenController 屏幕控制接口 + FiseScreenController 实现（ROM广播） - NfcController NFC控制接口 + FiseNfcController 实现（sysfs读写） - VibrationController 振动接口 + FiseVibrationController 实现（13种方案+音频） - SystemStateMonitor 系统状态监听（电量、蓝牙状态广播） - DeviceModule Hilt硬件抽象绑定 - 8个音频文件（res/raw/） - AppEvent 新增4个系统状态事件修改： - MainActivity 注册 SystemStateMonitor - HomeFragment 硬件验证demo（熄屏/振动/NFC/电量实时显示） Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
