fix(jobdanmark-search): emit the /scrape contract fields in search output (#340)

Adds additive normalization so jobdanmark search output carries the cross-portal contract fields: company from companyName, location as the city after the postal code in companyAddress (null-safe - a missing or null address yields null instead of crashing the search), and date/deadline converted from DD-MM-YYYY to YYYY-MM-DD with safe passthrough on unexpected formats. Native fields unchanged.

+> - Every result also carries the cross-portal contract fields `company`, `location`, `date` and `deadline`, derived from `companyName`, the city after the postal code in `companyAddress`, and the day-first dates converted to `YYYY-MM-DD` — `/scrape` Step 2 expects search output to include title, company, location, date, and URL. Native fields are preserved unchanged.
