fix(jobdanmark-search): accept a comma after the postcode in location extraction

The location regex required whitespace after the 4-digit postcode, but
live companyAddress values frequently read "2670, Greve" - those results
emitted location: null (7/30 in the review's live sample; 1/30 after this
fix), leaving /scrape's geography filter nothing to act on. Extraction is
now a helper with a comma fallback that requires a non-digit city start,
so a 4-digit street number never wins over the real postcode, and the
captured city is trimmed. Review finding F2 (2026-08-19).
