Add scrape/ingestion engine + validation, and 24h shift hour-range visualization

Scrape engine (Services/Scraping/): pluggable IListingSource (working sample + Telegram/Divar credential-ready stubs) → IngestionService (content-hash dedupe → parse → validate → review queue) → ListingValidator (completeness score + spam screen) → IngestionWorker (config-gated hosted service). RawListing gains ContentHash/Confidence/ValidationNotes; RawListingStatus.Flagged. Admin /Admin gets run-now, source list, confidence + flagged queue.

Hour-range viz: _HourBar 24h timeline bar (colored by type, overnight wrap) on shift cards, recommendation cards, and detail.
