Fix spurious decode errors with H.264 on native Viewer

[Wumpf]

Removes a previous attempt for lower latency that caused spurios decode errors, observed with ffmpeg 7.1 on Mac & Windows.

Also, fix retry-on-error condition: we were checking for the wrong kind of error in VideoPlayerError::should_request_more_frames.
This improves pausing on corrupt video data which sometimes may recover on decoder restarts.

the new tests are very unhappy about this? Needs a closer look.

ah ofc, the ones where we don't have a decoder bail now. Need to make the redraw condition more fine grained!

good test! :)
