fix: correct DOM.RIA URL slugs for commercial, garages, rent_daily ...

- kommercheskih → kom-nedvizhimosti (commercial)
- garazhey → garazhei (garages)
- posutochnaya-arenda → posutochnaia-arenda (daily rent)
- Add rooms category (komnat)
- Update normalizer fallback title for new categories

fix: increase ingest timeout to 300s and cap images at 15 per listing ...

- Prevents inline pipeline timeouts on listings with 40+ photos
- 15 images is enough for AI analysis while keeping request duration reasonable

feat: download images locally and ingest via multipart /with-images endpoint ...

- Update collector to support ingest_with_images using CurlMime multipart
- Crawler now downloads listing photos in parallel (5 workers) to temp files
- Fix photo URL builder: use photosnew CDN + beautifulUrl (legacy file paths are 415)
- Add fallback title generation in normalizer for PayloadSchema validation
- Increase ingest timeout to 120s for inline pipeline processing

Closes: photo ingestion via binary upload

Align payload fields with data_collector PayloadSchema ...

- Rename 'photos' -> 'images' (data_collector expects images: list[str])
- Add 'price' field matching PayloadSchema price field
- Add 'contact_phone' (first phone string, not list)
- Add 'address' (combined city+district+street+building string)
- Add 'area', 'rooms', 'floor' per strict schema
- Keep extra fields (price_usd, city_name, etc.) because extra=allow
- Remove 'photos_count' in favor of checking len(images)

Fixes photo ingestion — previously data_collector rejected/ignored 'photos'
because PayloadSchema only knows 'images'.

Improve photo extraction robustness and add logging ...

- Add _extract_photos() helper to handle both list and dict formats
- _build_photo_urls() now skips non-dict entries gracefully
- Fallback to detail.main_photo when no photos array is present
- Add photos_count to payload for easy verification
- Add crawler warning log when a listing has zero photos after normalization
- Prefer detail photos (usually higher quality), fallback to catalog

Fix city discovery: keep cities with -obl- suffix ...

- Remove '-obl-' from subpage indicators; cities like brovary-obl-kievskaya
  and vasylkov-obl-kievskaya are real settlements with region disambiguation
- Only slug starting with 'obl-' is treated as a region, not mid-string
- Increases discovered city count from ~307 to ~330
