"""Upload status-polling tests.

Covers two things:
1. Regression coverage for the queued-vs-processing template bug reported
   after a real deployment: a file sitting in 'queued' status (before the
   background trigger/cron picks it up) was rendering the same text as a
   genuinely in-progress parse, making the two states indistinguishable.
2. The real percentage progress bar (Ch12: total_lines is now counted on
   first pickup, so processed/total renders as an actual percentage
   instead of an indeterminate spinner).
