Fix(api): correct document parsing progress check logic (#6318)

- Fix incorrect progress check condition that prevented re-parsing of
completed documents
- Allow parsing for documents with progress 0.0 (not started) or 1.0
(completed)
- Only block parsing for documents currently in progress (0.0 < progress
< 1.0)

Close #6312
