jtricerolph b47258d47b Fix scrape submission race condition allowing duplicate background tasks
Two rapid POST /scrape requests could both pass the lock check before
either background task acquired SCRAPE_LOCK, queuing two sequential
scrapes for the same date range. The second would hit Cloudflare after
the first already succeeded, causing repeated retries.

_SCRAPE_PENDING is set on submission and cleared when the task starts,
closing the gap between the 409 check and lock acquisition.
