- Site audit tab (UI-SPEC C20): crawl_schedule, crawl_max_pages
(10-50 000), crawl_delay (100-5000 ms), crawl_keep (1-50) and
generic_anchors seeded with the en and pl lists; ranges refuse with
lagoon::validation.between on the screen and through the API
- the crawler reads its limits and generic anchors from the settings;
crawls beyond crawl_keep are deleted with their pages and issues
- seo:crawl [--scheduled] and the nightly schedule entry at 02:30
(P33-40): off does nothing, weekly runs on Mondays in app.timezone
- TestCrawlSchedule
