- restream.py: eliminar -reconnect_streamed de ffmpeg para evitar rebobinados al reconectar (el proveedor re-enviaba desde keyframe anterior causando PTS backward). El loop de Python gestiona las reconexiones con conexión fresca. - restream.py: eliminar _drain_queue del loop de reconexión para que el buffer de la cola cubra el tiempo de reconexión sin pantalla negra en el player. - restream.py: añadir buffer_server_bytes/secs/capacity a stats() y método _log_stream_event() para persistir eventos de caída y recuperación en BD. - models/stream_event.py: nuevo modelo StreamEvent para registro de fallos. - database.py: registrar StreamEvent en init_db. - api/admin/logs.py: nuevos endpoints GET/DELETE /logs/events. - Dashboard.tsx: mostrar reserva de buffer del servidor (capacidad + estado). - Logs.tsx: añadir pestaña "Fallos de stream" con tabla de eventos persistidos.
