chatgui: воспроизведение видео — FFmpeg-плеер + frameless окно

- videoplayer_engine: декод в worker-потоке (FFmpeg), A/V sync по аудио-курсору, seek с epoch-защитой от устаревших кадров - videoplayer_window: окно без рамки, drag-перенос, dblclick/Alt+Enter fullscreen, Esc закрытие, timeline + play/pause/close, авто-скрытие контролов - видео-баббл в списке: превью-кадр (jpg), play-оверлей, длительность, прогресс - превью извлекается после скачивания (video_extract_thumbnail) в фоне - mainwindow: синглтон-плеер, openVideoRequested → openVideo - CMake: HAVE_FFMPEG для vibechat
