fix(jobnet-search): emit the /scrape contract fields in search output (#339)

Adds additive normalization so jobnet search output carries the cross-portal contract fields (company, location, date, deadline with the 1900-01-01 NotDisclosed sentinel mapped to null, and url). Emits the public /find-job/{jobAdId} route and corrects the skill's own stale /job/ documentation, which redirects anonymous visitors into the MitID login flow.

+> **Note**: Every result also carries the cross-portal contract fields `company`, `location`, `date`, `deadline` and `url` — derived respectively from `hiringOrgName`, `postalDistrictName`/`municipality`, and the jobnet detail page URL. `/scrape` Step 2 expects search output to include title, company, location, date, and URL, and dates follow the `YYYY-MM-DD` convention of the other portal CLIs. The API's `1900-01-01` deadline sentinel (deadline not disclosed) maps to `null`. The native fields above are preserved unchanged.
