test(cli): cover Jobbank and Jobdanmark contracts (#148)

Jobbank and Jobdanmark each had only one narrow test, leaving required-argument errors, RSS normalization, JSON-LD variants, and malformed-page handling unprotected.

Add network-free fixture and subprocess tests for repeated RSS filters, description and ID parsing, stderr JSON errors, Bunli numeric validation, JSON-LD objects and arrays, optional fields, not-found pages, and parse failures.

The suites now cover eight Jobbank cases and six Jobdanmark cases without making live portal requests.
