[cuegui] Fix Last Line Output persistence in Frame Monitor Tree (#1857)

The Last Line Output column was disappearing after briefly showing due
to incorrect redraw logic in the `tick()` method. Changed to use
`redrawRunning()` instead of generic `redraw()` to properly update only
running frame columns (runtime, LLU, and last line).

This ensures the Last Line data persists and is visible for monitoring
frame progress, matching the behavior from previous Cuetopia version.
