[fix](load): fix incorrect progress on finished loads

[kaijchen]

What problem does this PR solve?

Issue Number: CIR-17562

Problem Summary:

Finished load jobs could show less than 100% progress because the status
was not reported correctly when any file scanner had
num_rows_load_total == 0 and num_rows_load_filtered == 0.

This fix ensures the status is reported correctly and finished loads
now display 100% progress.

Before:

| 1756660232981 | load_data_4_objects_large_high_column | FINISHED | 0.00% (0/1000)            | BROKER | ...

After:

| 1756660232984 | load_data_5_objects_large_high_column | FINISHED | 100.00% (1000/1000)       | BROKER | ...
