Sucukdeluxe 10528a2696 perf(ui): enforce 750 ms live update cadence
Use one 750 ms interval for running download snapshots, progress updates, the bandwidth chart, and the header speed sparkline across every queue size. Remove the extra active-download renderer delay and add timing regressions for small, medium, and large queues.
