wohnungen: fall back to scraper data when LLM JSON has nulls

Browse source 
Many listings die or 404 within hours of being published, and several
landlord pages render their stats via JS that our Playwright fetch doesn't
reliably catch. In those cases the LLM correctly returns nulls — but we'd
then show "2 Z · vor 30 min" and lose the m²/€/WBS info that the
inberlinwohnen.de scraper had captured authoritatively.

The list now coalesces: e.rooms / e.size_sqm / e.rent_total or rent_cold /
e.wbs_required take precedence; when null we fall back to f.rooms, f.size,
f.total_rent, f.wbs respectively. Boolean wbs_required uses `is sameas`
so an explicit `false` (no-WBS) from the LLM is preserved instead of being
treated as missing.
