fix(sdk): transferMedia 入口立即把 transferProgress 归零

Browse Source 
旧实现里 transferProgress 只在 transferFile() 内部才置 0，但
transferMedia 要先走 validateMediaFormat → aniConverter.convert →
getRemoteFileSize → prepareTransfer 这条数秒级异步链，期间字段还停
留在上次结束的 100。集成方 UI 一接上观察就看到旧值 100，体感像「上
次进度被带过来」。

修法：transferMedia 在 connectedDevice 守卫通过后立即 transferProgress = 0，
delegate 立即收到 didUpdateProgress(0)；后续 transferFile() 内部的 = 0
因 didSet 的 oldValue 守卫被自然跳过，不会重复广播。
