The progress bar was configured with Max=100 but we were setting
values in the 0.0-1.0 range, causing it to always show ~0%.
Fixed by multiplying the percentage by 100 before setting the value,
so 4/22 = 0.18 becomes 18% instead of 0.18%.
Also fixed SetComplete() to set 100.0 instead of 1.0.

The issue was that FFmpeg's out_time_ms field is actually in microseconds
(not milliseconds despite the name). We were dividing by 1,000 when we
should have been dividing by 1,000,000 to convert to seconds.
This caused the progress calculation to be off by 1000x, making it
immediately jump to 100% even though the job was just starting.
Also added comprehensive debug logging to track progress samples and
identify calculation issues in the future.
